if you missed my original post about the block i milled, go here:

http://forum.oc-forums.com/vb/showthread.php?s=&threadid=132621&highlight=critique

well, i got it leak tested and installed, though its not done yet (is it ever?:D )

currently keeping my duron 750 @ 946 1.92vcore at 5C over system temp with only one 8cm adjustable enermax fan on the heatercore, no shroud. its a 6" x 7 3/4" x 2" heatercore btw.

i just installed it so that's load after 18 min sandra MMX burn in. i'll crank up the vcore and overclock on this puppy to see what it can really handle.

sadly, i killed my 1600 xp when trying to install this the first time, as the mounting screws i used bottomed out in the tapped hole ( i believe) and it fried. i'll have to get another

here's some pics:

Everything

close up of pump and rad:

i plan to get some 90 degree elbows for both the inlet and 2 outlets, and angle them toward the pump so i don't have to have this mess of tubing that is crimping on me.

i moved some of the very messy wires so you can see the pump and the tee fitting right before the intake:

EDIT: just turned off the box fan by my system and closed up the sides (i dont' have my intake fans running right now) and my system temp at 41C (ouch that's hot :mad: ) but cpu temp at 39C!

ok, ran cpu burn for 3 hours while i was at my afternoon classes:

duron 750 @ 1020 MHz
1.99 vcore
system temp 33C
load cpu temp 40C

not the best - but i'm only using 3 of the 4 mounting holes for now, and aluminum, and one fan on radiator, which is slightly warm to the touch.

I'm thinking:

1. replace barbs on block with right angles (lose some flow, but have 700gph pump) and this will eliminate all my crimped tubes

2. lower the radiator about 1" and add a second enermax fan (right now only one fan, 92mm (sorry, think i said 8cm before, i was wrong), and the rad is right up against the top of my case = bad for air flow)

3. mill the bottom of the block to .125 or thinner (current = .250")

4. add some case fans to decrease ambient temp

5. make this out of copper (with some mods) and see how it goes

what does everyone think?


EDIT: just to note
- the Rad is a little warm, telling me there is room for improvement there (mostly in cfm's, i suspect)
- the block isn't very warm (for a wb/heatsink) which tells me there is enough surface area to take away the heat properly. it suggests i would benefit by (as i stated above) better metal = copper, and thinner base.

i've done some more testing (only on this duron though, i need to get another XP chip bad!!!) and at least I know my high 40C load temp was mostly due to ambient temp. Running CPU burn for 3 hours with a couple different ambient temps:


1.97Vcore 750 @ 1020 Mhz

ambient: 21C cpu: 29C

ambient: 26C cpu: 32C

back down the speeds: 750 @ 800 1.68Vcore

ambient: 26C cpu: 29C


yeah, its only a duron, but not too bad considering its aluminum, the base is too thick and the bottom isn't lapped. i did finally add a second 92mm enermax to my radiator though (both running about 3/4 of full speed) - shroud coming this weekend maybe.


going to an XP at 2.0V at 1800 Mhz, can anyone tell me about what wattage that would put out, and about what my duron is putting out now? And how to calculate C/W rating for my block? I also plan to get a temp probe this weekend to measure water temps.

i am thinking (hoping) to get similar results going from
(1) duron @ 1020 1.97vcore alum. block, non-lapped, .25" thick base
to
(2) xp @ ~ 1800 Mhz 2.0vcore copper block, lapped, ~.100" thck base.

what do you think?

Got my xp 1600 installed about 2 hours ago guys!!!

1600 AGOIA 0226 "Z"

clocks to about 1780 stable so far, not much past that....

not bad, but i still wish i had the AGOIA "Y" that did 1840 on air...


anyhow, didn' t change a thing from my duron setup, just put this processor in. Maybe tightened down the bolts harder (I tightened them pretty darn good...)

Here's a screenie for ya:

20_min.jpg


That's 1.95 vcore (reported in MBM) ----- 1.98 vcore (reported in BIOS)

at 10.5 x 169 = 1775 (1777 reported)

Man these temps are making me want to get my copper block done even faster!!!

Though i know my air to the rad is at least a couple degrees cooler than my system temp is, i just have no way to stabilize temps in here that well.....

looks good, but i cannot access the pics

yeah, i'll get to fixing them...

but you can see em in the waterblock gallery (the block at least)

EDIT: fixed the pics in this thread, but sometimes fortunecity goes down for like 15 minutes. If this persists, let me know...

Ok, all pics in all these threads should work now. PM me if something isn't working I can try to fix or just mail you the pics.




...so what do you all think of the temps?

now been running burnmmx for 1 hour 15 min and temp is still 4C above (reported) system temp ---> 43C and 39C

Temps sound fine. Don't worry about adding another fan on the radiator, just find a way to hold the one you have blowing as an exit.

I vote suspend the fan somehow afew inchest under the radiator blowing up. See my post:
http://forum.oc-forums.com/vb/showthread.php?s=&threadid=138678
It's not how much airflow, it's jsut that you have the minimum.

Also don't count the duron's out. They may not produce the same heat as an XP, but what they do put out is more concentrated.
Like I said, suspend the fan under the heater core blowing up and out. They main thing for you is to fix those ambient temps!

well i since have added a second fan alread, and i suspended them about 3/4" above my heatercore still blowing down. but I have read and agree with you post, because i only got about 1C difference running both fans at full or running both at nearly lowest speed (pretty silent).

My plan is to cut a plexi top with two holes for the fans and move the RAD down about 1 inch from the fanse. then make a plexi shround to exhaust the hot air through the back of my case above the psu.

I could blow up and through the core, but my case temps usually run hot - see pic = 37 - 42C when i have the side on!

Thanks, My concern would still be why your case temps are so hot. What kind of intake/exhaust fans are you running?

looks pretty good to me, the temps don't seem bad to me...pretty good on a homemade block...congrats man

well, the sides are completely off right now. And they won't be going back on anytime soon. i'm just running one that's half blowing through some holes by my 3 hDD's but its not too effective (just enough to keep the hdd cool though) and one half stuck in a 5.25 bay blowing on my really hot pump.

but i've never trusted this mobo's temp sensors. my kt7a board INSIDE a case with only one fan on top of my desk shows 27C. that case is a little cooler, but there is no way my main rig is that hot. I think its more like 32C or so.

but here's what i did for now:
turned on my box fan (on low setting) next to the back side of the mobo. Case temp down to 32C and load temp at 41C now. but i backed down the speed to 1740MHz cuz it blue screened after 3 hours at 1777Mhz. core volts still at 1.95-1.98 though.

thanks, and i think my temps are pretty darn good, considering its an aluminum block with a thick base and my hoses are kinked liked there's no tomorrow
