Cooling a 6600 Quad

I just used sandpaper when I lapped my e6600 and e2160. Mount the paper on something flat (glass block for example) rub the cpu onto the sandpaper with an even pressure, and keep rotating it every 10 seconds or so,

do you just use sand paper?

Just search for lapping kit on that auction site.....here's my 2 little beaut's which i done dry and just straight back and forth motion ( only use figure 8 motion if there is a good excess to be removed ) and then hand polished.

Selected sheets of Wet'n'Dry silicon carbide paper by 3m, very accurate grit sizes. And a piece of thick glass, or well supported on a flat surface. Window glass or mirrors are good, they come from a float process and is very flat.

I always 'blue' the cpu or heatsink to check for high/low spots first. Just cover the surface with felt tip and gentle pull it over a sheet of thin photocopier paper that's on glass. The 'blue' comes off where it touches without any damage to the surface. If there's a high/low point you'll soon see. Once/if its polished the reflection from grid paper will show any surface distortions quite well.

What Vcore are you guys running?

I just dropped mine from 1.25 to 1.15 and the temps are lower at load, im not overclocked mind you.

Reckon i should just leave it lower? Will it do any harm?
 
Wont do any harm. It'll prehaps be less stable though.
You'd have to test tbh, run something like Prime for 24hours or so at that voltage and see if its stable. If it is, stick with it, if it isnt, return it to stock. :).
 
lapping seems a lot of hassel. Ive already spent 2 years sanding things over and over again in tech at school lol. Is the 120 extreme one of the worst for needing lapping?
 
It is bad, i emailed thermalright who told me that they were designed that way and my idle temp of 52 and load temp of 76 were perfectly normal.

So out come the sandpaper and after a few hours my q6600 now idles at 40 and 68 loaded.

Hopefully it will drop by a few more degrees when my as5 arrives

Is 1.275 stock for these?

I dont think Coretemp and CPU-Z are reading the Vcore correctly (for me anyway).

I set the Asus board to auto and i think it set the Vcore the 1.375, i heard they do this by default and it just adds unecessary high temperatures?

Cheers.
 
You serious???

You guys are seriously telling us that you "SANDPAPERED" a £200 chip ??? !!!!!
Gee-Whiz, you guys ever heard about static electricity and earthing youself? How come the grinding process didnt blow the chip? Now that would be an expensive mistake !!!

So after all that you get the CPU flat. How about grinding the bottom of the heatsink on the Tuniq Tower or whaever? Same method?

So now you have a flat bottom of the heatsink and the top of the cpu. You bung on some Arctic Silver (I assume?) and put the HS on top. How can you know for sure, when tightening the heat sink up onto the chip and motherboard that you haven't squeezed more of the Arctic silver out of one side than the other and as such have got bits of the CPU not covered in the AS. How can you hold the Heat Sink perfectly level above the chip, just prior to touching the AS on top of the chip prior to tightening?

What you guys are dong is very interesting, though dangerous !!!! :eek:

Interested in what you havet say guys.

Cheers, Steve

They're pretty hardy are cpu's, just don't drop them. Its wise to use some masking tape to seal the plastic back plate on. Stop anything getting in, IHS aren't all that well sealed. Yes you should lap both surfaces. Methods vary, with quad cores they recommend a thin line of TIM across the cores. The pressure forces the TIM to spread out easily, its only supposed to be a few microns wide, thats why too much is a problem. It doesn't need to cover the IHS to the corners, just well cover the cores. Most of the HSF have springs to even the loads at the corners, you should still pull down the bolts diagonally a couple of threads at a time, to keep it even.

Not a clue. :p.

Look for the VID value thats the default Vcore factory set.
 
Cheers guys, when they say a Q6600 is rated at 62 degrees then, does that mean the coretemp temperatures or the "CPU" temperature, as shown in something like Asus Probe?

Do you see what i mean?

Thanks

Would love to do that to my Q6600...... but I'm waaaaay to scared :o

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. :D

I see what you mean ;)

The 62 degrees is the "CPU" temp not the individual inside the core temps.

so for example if you had cpu temp 55c, and the 4 cores were showing around 70c each in coretemp, thats fine.
