Cooling a 6600 Quad

Kingy1968 · 5 Aug 2007 at 22:12

Ive lapped my Q6600 and I paid £235 for mine :confused:

I kaked me pants when I did it but now I wouldnt heasitate to do it again as mine was convex and wasnt flat at all..

Temps have dropped about 5-6oC

You see call me demanding but I'd be wanting a bigger decrease than that, has anyone else had a better result or is that about the norm?

38c load on air

Screenshot please

Yes used coretemp. Even running the latest PovRay (multi core beta), core didn't go above 40 oC (all cores at 100%). No lapping, just a thin even smear of Artic Silver 5.

How do I post a screenshot ?. Will this forum accept image downloads or do I need to host somewhere ?.

Regards

Unless the chip\heat sink is in a bad state I'd say even 5-6deg is a good result. I went through a phase of doing the same a couple of years back and never saw any improvement over that, even with water blocks.

what is interesting, is that the current fad with water blocks is to actually bow them outwards. This is getting some very good results over standard as it's ensuring tight contact over the chip area on the spreader...

Depends on the game and by time hes com out of it and looke at the temps they would have obviously dropped.

You are spot on.....I'll correct my statement to say 58 oC all cores @ 100% !!

I'm suprised how fast the temps drop when coming out of an ap (just 1-2 seconds)

Sorry....

There's nothing to it m8....sooooo simple to do and when you do it that once and see how easy it is you will want to do the next chip you get your hands on!....no need to be scared.

Here's the results of an e6600 i did yesterday temp is @ load.... while waiting for the G0's

take note of the time it took at bottom of pic.

Because in normal circumstances its totally unnecessary and a kinda costly.

I'm surprised either AMD or Intel hasn't jumped on the bandwagon here.
Not for the everyday chips, but the extreme editions.
Imagine Intel Core 2 Quad Extreme Edition becomes Intel Core 2 Quad lapped Extreme Edition.

I take your point that you are risking any chance of ever returning the CPU, and may damage it when lapping but thats a fair bit to loose.

Like the difference between a cheap and top notch air cooler.

Or why pay the extra for a top notch air cooler, when a large percentage of the base isn't in contact with the CPU.

Just the change the topic arguably slightly more on course, would a Zalman CNPS9700-LED be ok for a Q6600?

Did you see reviews?

The results seem mixed....

I've been having big problems lately with my QX6700 overheating. Upto 90c load and in the 70's idle.

After installing this cooler with Arctic Silver 5 (on EVGA 680i Mobo) my CPU idles at around 57c (according to TAT) and rises to 73c load. Still hot, but a lot better than the stock cooler.

and

I took great consideration and research time before deciding on the Zalman CNPS9700. I have a Intel Core 2 Quad QX6700 and I needed only the best CPU air cooler to keep those 4 cores in check. This thing amazed me from the word go. Firstly, the build quality is amazing. It shines, is glistens, and oh yeah, its huge! Had no problems fitting it onto my nForce 680i Motherboard though like some other reviewers. Other reviewers have been pleased with this cooler keeping their E6600's at 40C. I'm pleased to say, this cooler keeps my Quad Core at 31C on Idle. Thats an amazing temperature to achieve with this type of processor. Also comes with a nice fan controller to simplify things. Its a little noisy on full but a little adjustment lower and its as silent as the wind. My verdict: Amazed all the way. Would recommend this baby to anyone, with any processor. P.S Measure up your motherboard and case first, because this thing is a beast of a cooler. It stands tall, like it should.

It should be fine

Just to re-inforce the quote above, the 9700 is VERY BIG.
Pictures dont do it justice.
I got one to cool a C2D E4xxx at work.
Very big. Very cool looking. But not as quiet as you'd think.

God that really did need lapping didn't it, I'm gonna do my E6300/E2140 pretty soon, I'm sure there the same as that chip.

w3bbo · 10 Aug 2007 at 07:40

Thats deffo concave - lapping it will improve temps a lot in your case.

BoomAM · 10 Aug 2007 at 10:08

Are all 6600s concave?
I dont want to lap mine if i can avoid it tbh.

If thats a Thermalright Ultra 120 its probably the base of the cooler that needs lapping more, they are legendary in their concavity.

Won't hurt to do both tho

vocch · 10 Aug 2007 at 13:04

Although my Thermalright Ultra 120 was convex and my cpu was concave still made crap contact my above results were with lapped Thermalright Ultra 120 and before and after unlapped/lapped cpu.

Not surprising! Unless they were laser machined to match the convexity of one part would not have matched the concavity of the other.

I'm just saying that try lapping the Heatsink first, the heatspreader on the CPU is less likely to be as bad. But of course check it and then do it if necessary.

Well if the Heatsinks is made like mine convex and the chip is concave then lapping the heasink would only make it worse as in even less contact?....unless there is no QC on these Heatsinks and they are throwing out both convex/concave.

Edit: After a little search found that The convex bow in the surface was, deliberately put there by ThermalRight's engineers...it was a deliberate decision...so they are intentionally made to bow outwards!.

Wizardskills · 11 Aug 2007 at 00:35

Im using a coolermaster GeminII with 2 120mm fans attached on my q6600. The four cores idle at about 40 ~ 45 degrees and up to about 55 ~ 59 when playing games. Asus probe also reads the CPU as arround 29 degrees idle. Ill post some screenies when i get my RAM back from OcUK.

Here is a pic of the actual heat sink with the fans on
