hot water

[portorock]

how do you guys do it? I see people getting down to 32C air cooled. I have the Maze and cooling cube with 1-120mm/132cfm, 3-80mm fans. The case intake,one blows right on the cpu from the side of the case, and the other blows into the cooling cube radiator while the 120 sucks air out. The lowest idle I can get is in the low 40's and high 40's-low 50's load. Why am I cursed to have such a hot computer. I do have 4-pci cards and one vid card in, but they can't be producing that much heat can they? Please help, I'm jealous of all those low temps

portorock,

Is your computer in a warm room? I moved my box from the upstairs to basement and now it runs much cooler. My basement is ususally around 24C (75 F) whereas my upstairs room was more like 25.5C (78F). Also my basement is a large cool area so it takes longer for the room to heatup vs. my small upstairs room.

another cause could be your thermal paste and/or air bubles

[portorock]

Using AS2, reapplied the block a couple times to ensure everything was good, also, my comp is in the coolest room in the apt. I usually keep temps about 75F, but it is a small room

[portorock]

I also hacked an old HS and AS epoxied it to the block with the side fan blowing on it, no change

[dimmreaper]

What size pump are you running? It may be that your pump does not have enough flow at the head it has.

[Anthrax]

If you have more air going in than out, or vice versa, you could be dealing with too high, or low of pressure. This will drastically effect your tempertures.

[r0ckstarbob]

what are your vCore and I/O voltage settings at? you and i seem to have similar systems. maybe i can help.

can you take some pics of your system and post them?
of course it may just be a bad thermometer too...

what are you using to measure your temps?

[Warlord2]

how are you getting those temps?

your motherboard could just be off

I had a ka-266-r and if showed my temps to be alot hotter than what they are now with a ak31 shuttle......

grr or maybe those temps where right and my temps now are wrong=/

I may never now=[

one thing I did when I moved to the new board was apply more force on the cpu with the waterblock

you have to have good contact with the cpu or you temps will be high

[Crappy]

I see you are using the the KT7A. If you have a newer bios like version 3R, then that is what gives you higher temps at idle.

Here is some info from http://www.viahardware.com/faq/kt7/kt7faq.htm

With previous BIOS versions ABIT set a bit in the BIOS CMOS (offset 52 bit 7) to "1" to enable the ACPI "HALT" function and cool down the CPU temp in idle mode. This, whilst allowing cooler CPU operation, is against the advice of AMD and VIA. Under earlier AMD processors, however, this modification allowed the system to idle cooler and had no ill effects. However, it was been found with newer 133MHz FSB processors running at 1333MHz and higher, that this software cooling can cause severe stability problems - especially under Windows 2000. As a consequence, in all ABIT BIOS releases after version 3R, ABIT have set this bit to "0" - the value recommended by AMD and VIA. This allows the motherboard to be stable with all AMD processors at the expense of an increase of 5-10 degrees Centigrade during idle (from approximately 35 degs C to 45 degs C). This will not harm your motherboard or processor.

[portorock]

I'm using Via hardware monitor that came with the sys. I also have the Eheim 1250 pump w/317gph. The bios is 3R. I do have a small reservior. It's a cleaned out bottle of laundry detergent, it holds about a gallon or so of H2O. Could that be too small, I would suspect a bigger reserve would be harder to heat up/cool down.

Thanks for the advise

[portorock]

using the Via hardware monitor, my temps read 42c, but in sisoft, they read 35c. Which should I trust more, the one that came with the mobo or sisoft?

[r0ckstarbob]

crappy

i have the Bios 3R. and while i had temps around 40-45 when i started, by the time i got done with all my mods i'm at the temps you see below in my sig.

he's getting those temps WATERCOOLED. i bet his system wouldn't even POST with a conventional HSF combo.

no, theres something definately amiss here.

THAT is a very good question. anyone?

[portorock]

I just d/l MBM5 from viahardware.com, I set it up and noticed that there are three VIA686b sensors, 1,2,&3. Which is the CPU, and what are the other two for? 1 reads 23, 2 reads 33, and 3 reads 43 degrees C? WTF!!! The funny thing is before I watercooled, I was running about the same temps, but they would increase at a faster rate.

[Crappy]

CPU is VIA686B-3
Case is VIA686B-2

[Crappy]

OK here is another thing, I'm just throwing out ideas.

Maybe your pump is moving the water too fast for it to pick up the heat from the waterblock and not sitting in your cube long enough to cool it.

I have seen this happen before.

[portorock]

How could I restrict the flow, put somthing in the line near one of the junctions, but what would fit without being sucked into the sys?

[Crappy]

You could use a wire-tie or hose clamp on the outside of one of the lines.

Or you could put a loop into one of the lines but with that 1250 pump it's going to be hard to slow it down that way.

[rodvon]

I take it that your pump is in the res. if so what the wattage that the pump is puting out you mite want to try a inline pump. I would also play with flow to try for a inprovement.

[r0ckstarbob]

you could split the hose you have going TO your CPU in half with a splitter (not literally cut it in half but you know what i mean) and send it right back into your reservoir.

that would not only slow the flow to your CPU down by halfing the amount of water that got there in the first place, you will have just made another loop for the water to cool down before it gets pumped out again... you could even kind of decide how much speed you wanted pulled off of it by the size hose you put on it.

hmmm something to think about i guess.

please excuse the crappy ascII

[portorock]

Hmmmmmmmmm, never thought about that, I was thinking about actually putting something in the line, but then the risk of whatever is in the line coming free was a prob, your's is a much better solution. I'll try that and get back with the results.


Thanx again

[r0ckstarbob]

just remember... the top of that loop will have to be as high as the highest point in your regular system (probably as tall as your cpu) otherwise it'll just flow directly into your shunted secondary hose because it's lower. that is, if they're the same size. if your secondary hose is smaller in diameter then the one going to your cpu, then it probably won't have to be as high up, but it will still need to be elevated i think.

hmmm. runnin numbers... runnin numbers... runnin numbers...

i'm curious to see how this goes. i really hope it works for you. keep us posted.

[r0ckstarbob]

ya know, somethin else i was thinkin about.

if you do this second hose idea, it seems the ideal place to put a regulator of some kind. something you could screw closed or open. if you closed it off, the water would pressureize off in the secondary tube, stop moving and the primary tube would get all the flow. if you opened it up a little bit, you could bleed a little off the primary with the secondary... open it up ALOT and cut the flow to your primary in half... do that and you just made yourself a variable speed water pumping system. that way you wouldn't have to change hoses or anything everytime you decided to increase/decrease the flow to your CPU. you could "tweak" it to it's perfect pumping speed.

not too shabby to think about.

and we love that word "tweak" don't we OC'ers....

heh

[portorock]

OK, here's what happened, put the T in the line, temps went up b/c the new line was pulling too much water through it. Took it off and redid the block(lapped and AS2), now my temps are stuck on 44C, not bad, but I want more. I can't help it if I'm greedy. Core V is 1.74

[portorock]

I was just thinking, I am constantly running UD Agent, that's probably what's causing the temps to stay high, I'm gonna cut it off for a while and see how the comp acts. Update ya later

[r0ckstarbob]

1.) is that under load or idle?

2.) are you using arctic silver thermal paste?

3.) you said you re-lapped your plate... you know that thing should be so lapped that it should just about have a mirror finish right?

4.) which way is your fan pointing on your radiator?

is it

a.) fan---> radiator ---> ouside the case
or
b.) radiator<---- fan <---- ouside the case

one way or the other, that fan should be blowing onto your radiator, not sucking off of it. dunno what you have but figured it would be good to ask at this point. and if you can, answer b.) is going to give you the best cooling on that radiator...

glad the mod worked out for you. lets see if we can't get your system to reasonable levels now...

please do. this has caught my interest.

[portorock]

Well, temps dropped by 3 degrees, both load & idle. Am using AS2 on a highly lapped block. Since my rad is external, I have a 120mm sucking and an 80mm blowing. On top of that, I AS Epoxied a portion of my old HS onto the block with an 80mm side fan blowing right on it. I also have an 80mm intake at the bottom of my case. I guess I'm just stuck with a warmer than usual TBird.

[portorock]

here's my case
I know it looks like sh*t, but everything is behind the cd-roms, and out of the way of the fans

[portorock]

here's my block w/HS

[portorock]

and finally, my side fan

[r0ckstarbob]

i dunno man. somethin still smells fishy. if you have a regular HSF i'd bolt it on just long enough to get a temp reading and then email both abit and amd with your problem. they might have a fix for you. the temps you're getting right now are moderate for an aircooled system and absolutely hideous for a watercooled setup.

the reason i suggest putting a regular HSF on there is because if you email them and tell them you have a watercooled setup they're liable to laugh in your face, tell you that thats not factory recommended cooling solution and to go buy one of their recommended HSF combos. besides, using a regular HSF, you're going to get some REALLY high temps which will likely put you well ouside their own recommended safe operating parameters and warrant their attention.

i've had good experience with both these companies when i had questions that couldn't be answered anywhere else. extremely helpful. in fact, the first Tbird i had on this system was doing something similar, that is running quite warm. i emailed amd and they had me send the chip back to them and then sent me another one after they tested it and found it below specs. not too shabby if you ask me.

i mean it's totally possible that you just got a bunk chip. you know how they make these things right? the manufacturing process isn't perfect. thats why some chips will OC better then others. they'll produce a batch of 1300 chips actually rated to work at say (for example) 1500 with a (+) or (-) of around 100mhz to account for the errors in production. then they'll underrate the chip to 1330 to ensure that they're going to produce a chip that is capable of 1330 without having to test all of them. its that (+) 100mhz safety margin that we as overclockers hope to exploit and get out of our chip.

sometimes in the manufacutring process though, there'll be a slip-up and a chip thats rated at 1330 will actually max out at around only 1375 or 1400. that means just running the thing stock out of the box, you're already pushing the envelope and will get higher temps as a result.

i dunno. email both companies. see what they say. can't hurt. worst case scenerio, you stay where you're at and nothing changes. best case scenerio is that one of them has a fix for you.

as for me, from here, i'm stumped.

good luck

I changed the entry for registry #52 to EB, and my temps plummeted to 33C idle, I remember trying to do this awhile back but it had already been set. This time, it was not on EB but 6B. It's obvious that this change helped out a lot. 33 is a hell of a lot more reasonable than 43. Thanx to all that tried to help, especially r0ckstarbob who stayed with me through this horrifying ordeal, "I love man," but I bet I'm still not going to get your Bud Light. Thanx again.

[r0ckstarbob]

SHA------WEEEEET!!!!!

i love you too man. stay the hell away from my beer. :D

re-lapped your plate? whats this mean?

to lapp your plate... to make sure the surface is smooth and flat by sanding it.

to re-lapp your plate... to do it again.

[Newguy123]

ahhh i see :)

Does this need to be done to a brand new Maze 2?

Thanks much

[r0ckstarbob]

i would recommend doing it to absolutely anything that is being applied to your CPU to ensure the best possible connection between it and your heat removing device, whatever you choose.

[portorock]

I'd recommend doing it to any heat transfer surface, such as heat sinks and waterblocks, however, if you dare to do it to the proc, you're on your own. Lapping makes the surface flatter than it may have been, thus improving the heat transferring ability. You can do it to the HS on the North bridge, like on my mobo, or on video cards, and even the small waterblocks for those same components. It does help.

[Newguy123]

I know its in Reg edit but where do i go after i am in Reg edit Whats #52 to EB mean? changing the Entry Registry what does that do?Can this be done on a Asus a7v? i have a 800mhz Tbird in there with 1.75vcore and my temps are also at 48C idle i just set up my water cooling today got all the air out put in the water wetter and here i am now.


Thanks

[portorock]

This website has the info you need http://www.viahardware.com/faq/kt7/kt7faq.htm

It's the WPCRSET and WCPREDIT

[Newguy123]

Alright i found it, What are the adjustments u made to make the temp go down that much?? I changed the number from 6B to EB and made it final but still getting nothing. My temps in bios are the same as the temps in Asus probe 50C idle at 1.75vcore.

Does anyone have any other info as to why my temps might be so high. My maze2 is seated on there pretty good i tightned it pretty good i mean the springs that came with it are all the way compressed thats how much i have it titened. Is that a problem that its tightened too much?

Thanks

[portorock]

You have to wait a while, plus, it only works when the sys is idling, it doesn't do it all the time, if you're playing games or running f@h or similar cpu intense progs, it's not going to do jack, but ordinary surfing and what not, you should see a difference. Make sure you follow the dirrections to a tee( I don't mean to insult you, but I have fallen victim to this prob b/c I think I know so much about comps, just trying to cover all possible angles). If it doesn't work, I'm sorry. Not all things work the same for everyone, if that were the case, we'd all be awesome oc'ers.
