40c IDLE???!?!

[grindee]

Hi, I have a dual radiator setup, my wb is 19c, and the water is quite cold in the res. but for some reason i get horrible temps.....im not sure why this is, perhaps as3 not settled in yet? or restricted flow? all i know is its about 40F outside, yet i have bad temps, ill wait and see maybe if the temps go down once as3 settles. Any one else have any ideas of why? (the wb is screwed in to the max) THank you.

what part of your w/b is 19c? that's pretty impressive in itself, sounds like you're not getting good heat transfer between the chip and the block. what block is it? did you lap it? and what are you doing with dual rads? how do you have them set up? what are you using for a pump?

neeeeeeed more info!

[goatzool]

just out of curiosity, is your waterblock retained by springs or just bolts? I think the springs on my gemini make sure that there is 100% contact between the block and the processor, while without them, you could have pressure on an edge.

[grindee]

ok the maze 3 is lapped down to 600 grit and the themp censor is under the wb its the enermax psu one hehe and i have 2 120mm 130cfm fans push/pulling air thru the 2 rads with a shroud thats 1.5 inches thick both sides. and the room is pretty cool thats why the waterblock is so cold prolly too. the water is very cold to the touch. the pump is via 1300 and i just check the flow if ur a mathematician mab u can figure this out its like 1 inch high from the water , horizontally, it pushes the water about 5 inches.. seems purty weak to me.. could the flow be weak?
we removed some as3 from the chip there was a lil too much, the as3 over time tho sets right and the excess will pour out, the wb is on TIGHT , the springs are flat. hope this helps lol :D

yup it sounds like you dont have the wb on right, 40c is horrible for that temp. try remounting the block. Oh yeah if your waterflow is REALLY bad you will get bad temps too, I hope you set your rads up in parrallel, if you didnt thin your restricting your water a ton.

[Warlord2]

lol that looks almost like the same setup I have, same pump, same fans. But how do you have your rads setup? parrallel or series?

[Ottoman]

my setup is pretty close tom, same pump, same block, but i'm using a heater core i get temps in the low 30's...


try screwing till the springs are fully compressed

[Lt. Max]

the springs are full compressed (i was just over at his house now got home hehe) and the wb is on tight. the rads are with home made y splitters that i made i bought T's from home depot and wit soldering iron redid the plastic eheh. u think ghetto Y's could mess up the flow ??

[Ottoman]

sounds like u melted them and they deformed and became restrictive.... take it apart and push water through them and see what happens

[Lt. Max]

well i looked thru them they dont seem restrictive to me.. i guess thats prolly what ill havta do tho, if i can find some REAL y splitters first, i dont wanna order online tho cause i ordered too much my moms gettin ****y. anyone kno where to get y-splitters Locally ?

max

[Warlord2]

man I still think the block isnt on right or something, even if a hair got inbetween the cpu and waterblock will mess you up. I say redo the block. For my Y spitter I used a copper T so it didnt hurt my flowrate at all. Oh yeah maybe the probe wont let the block make proper contact? Ive seen that happen before.

[grindee]

alright i ordered some y splitters :

These better solve this problem.... :D. I reseated the wb already today, no help. its screwed in all the way, and there are springs, not just bolts.

[Deus]

it seems that if your waterblock is at 19C, then neither radiators nor flowrate or any of that could be the problem, they are cooling the waterblock well, that is their job. the problem has to be somewhere between the block and the cpu, maybe you are using too much as3...too much can be as bad as none at all. or possibly there is something wrong with your temp probe. do you have a hsf or something to test with?

[Warlord2]

hmm try shooting a house fan at the cpu, if temps go down a ton thin your probe is just about worthless or is not touching the cpu at all and just taking the temp of the hot air under the cpu. I REALLY think its just your block not making good contact or maybe your sensors are out of wack.

[JFettig]

warlord is correct, it could also be that your not mounting the block correctly, it sounds like yoru compressing the crap out of the springs, allowing it to be uneven... if they are totally compressed one could be tighter than the rest...

If all springs are fully compressed, that would mean that the waterblock would be even. :eh?: Unless the springs are different lengths. :)

Just follow what everyone else has said, and see if that fixes it.

[JFettig]

no not exactly
thats not at all correct, just compress them ALMOST all the way... so theres like 1 turn tll they are compressed

The sensor is not in between the core and the WB is it?

[Warlord2]

lol if it was between the core and block thin he would have a smokin cpu by now.

[Lt. Max]

the temp censor i wedged under the cpu and wb after we put it on to see if the wb might b getting warm. we will try messing with the tightness of the block see if it does anything..

[Warlord2]

wah? under the cpu too?? how you manage that? is the cpu sitting perfectly flat?

[Lt. Max]

well i dont think its on the cpu, the wb goes a lil over the edge of the cpu so there was room between the wb and the mobo to jam the censor in there.. that didnt afect the temps cause it was already 40c idle b4.. well most likely the temperature censor is just wrong thats what i would think..

[Ottoman]

when i mount my WB, i do it like an engine header...

i screw them in diagnolly...

1 2
3 4

I do 1 and 4 for a little bit, then 2 and 3 for a little,
and go back and forth till they're all done

I guarantee the springs are different lengths. Do what maskedgeek said and loosen up the nuts until the spring are almost compressed, but not completely. Also, pull that temp sensor out. It's not gonna help you get cooler temps, just tell you a temp.

What kind of surface did you lap the block on? it may be smooth, but not flat. Check it with a good machinist's rule. They are very flat.

[masitti]

Just measured my springs, and they are all the same lengths, that is why I was asking. Although it is probably different.

[NeoMoses]

ok, i should have clarified. Your springs are probably the same length when measured with a ruler, but not a micrometer. And, once they are compressed fully they act just like a bolt. So, just imagine that the springs are: 0.999", 1.000", 1.000" and 1.002" long. By cranking the springs all the way down, you could easily have the block cocked slightly on the CPU, leaving an air gap of about 0.001", which is HUGE as far as thermal resistance is concerned. However, by leaving the springs just short of compressed, there is much less chance of this happening.

[jmuma]

Make sure that the waterblock is not rotated around the wrong way. The Maze 3 can be mounted 180 degrees the wrong way without really noticing it. The problem is the block catches the cpu mounting socket just enough to hang it up a little. You will still be able run, but your temps will be bad. Also what are your ambient temps? And are you using the motherboard sensor or cpu sensor?

<- If you look at my avatar you can see what I'm talking about with the mounting socket.
