E6750 + GA-P35-DS3R + Zalman CNPS 7000cu-LED

[Phunk0ne]

I've recently upgraded from a Athlon XP 2600+ with 1GB of ram and a Radeon 9800XT 256MB
to an Intel E6750 with a Gigabyte GA-P35-DS3R, 4x1GB A-Data Extreme edition DDRII-800 (PC6400) and a Radeon X1900XT 512MB.

With this new setup, I want to re-use my Zalman CNPS 7000cu-LED. I bought the support clip off ebay for this.

So I am wondering if anyone has any experience with something comparable, maybe the CNSP 7000 Alu-Cu version on both stock speeds and overclock speeds and what your temperature readings are on both settings

i.e.

stock/overclock
stock volt/oc volt
Idle/Load
ambient temp

and this this cooler better than the standard HSF from Intel?


I haven't tested this set-up yet, I am waiting for the graphics card to come in this friday.


Thanks

hmm, the CNSP 7000 is becoming a little dated, but it should still beat the stock Intel cooler. You should still be able to break 3GHz without breaking a sweat. The good thing about GA mobos (I have one too) is that they auto-adjust cpu voltages for you, so just leave the voltage on auto and tweak the FSB.
Also make sure your RAM ratio doesn't push mem clock speeds too far over DDR2-800. I'm not familiar with your RAM choice so I wouldn't suggest anything too far beyond stock speeds.

I Lapped my CNPS 7000cu to a mirror finish. Hopefully this will help to get the temps down some more when I am going to power this baby up

It might be worth lapping the processor's heat spreader as well. Mirror finish isn't as important as a very flat surface, but nice work either way. Check out the thread about the E6750/GA DS3R combo - its like 14 pages long now and has some great information.

I was thinking about lapping the IHS as well, but I want to test this out first with the lapped Zalman cooler. The reason why I am using this cooler, is because I am completely out of dough, broke beyond any means to buy the cooler I want (U-120-Extreme)

I will check out the E6750/GA DS3R combo thread, thanks!

Generally thermal paste makes up for any unevenness in the cpu or heatsink surface. What to watch out for is the air bubbles that might get trapped within the paste itself during installation. The best way to avoid this is to not "work" the paste (by spreading it around before attaching the heatsink). Just apply a rice-sized dab in the center of the cpu, and press the heatsink down evenly, then secure firmly. Just my 2 cents on that.

well, so far. I tested with orthos and stressed it would not go beyond 58C. AS5 still has some more hours +160 to go before working optimal? (200 hour break in period?).
But I am happy as it is now

I used to strips of tape and taped it off but for one small strip that goes right down the middle. Added AS-5 carefully, removed the 2 strips of tape and "et voila" A nice straight line of AS-5 goodness
I looked it up on youtube and google how people did this trick exactly. It has worked. Let's see if the temps will go down a little bit more after a week or so?

dflynchimp: thanks for the tip

I'll see if I can get a mild OC without adjusting the volts to get the cpu to 3.2Ghz next week, need to apply AS-5 under the MB heatsinks.

Well I finally took the step to Overclock my E6750 @3.2Ghz. Stock volts for cpu and MCH.
Using my lapped Zalman CNPS 7000cu-LED cooler.

Ram @ 4-4-4-12 2.0V 400Mhz
CPU Host clock @ 400
1:1 FSB ratio

Idle C0/C1 - 31C/32C

Stress test Orthos after 5 hours

C0/C1 - 59C/59C

I'm fairly happy with this, but it makes me curious what temps people get with intel's stock HSF?
Anyone?
