should i lap my quad im @3.4ghz watercooled and my temps are idle 1.44v core0-36,core1-30,core2-36,core3-29

prime95 load 1.392v core0-55,core1-50,core2-55,core3-49

many thanks in advance
 
DO you NEED to? probably not.

Would it be a good learning experience and provide better temps absolutely yes.

Will you see higher clocks? Maybe 100Mhz more I would not see much more especially on a quad.
 
If you do get 3.6 out of that then it will most likely still be below 70 degrees, 3.6 seems to be the most you can reasonably squeeze out of a q6600 on air.
 
I personally wouldn't bother

Lapping sometimes gives better contact for better heat transfer, but I think in most cases this is when the IHS isn't flat.

Even then it's a few degrees.

Also doesn't lapping void the warranty?

Not sure what you learn by doing it either :confused: how to sand a piece of metal? :p
 
It`s one of those many little things that can add together to give an overall, perceived, performance boost.

Lap.

Type of thermal goo.

Application style of thermal goo :p

1 cooler over another.

wc block brand.

wc setup.

Type of mobo used.

Type of memory used. (and standard of)

.. and some other things.

.. all these things add a little % to what u can possibly get. If 1 of them isn`t respected, it `can` make some of the others a waste of time.

Arguements sake, if the whole installation is religiously done, u could get... I dunno 5% performance gain ? if u lucky ? temps in general would probably slide 5-10% (all things above considered).

.. then u could be thrown all out of whack cos the cpu u got isn`t the best out of the batch.

It`s a hobby thing, it`s a perfectionist thing, on it`s own I don`t think it`s worth the trouble. Combined with all the other things, plus having a great interest in doing it - I think it`s worth it.

Tbh i think you must've done something wrong then

i doubt it. I think it's because my cpus were pretty good to start with. when i lapped mine, the copper started to come out from the centre, not like some other cpus i have seen that the corners are higher. I have checked my lapped cpu with a blade and it's flat, dont think any other things could go wrong?
 
Before u start to lap there are a few things u need to consider first. Are u prepared / aware that u will void your warranty, secondly lapping would only help when the base of your CPU / Heatsink of cooler isnt flat. U could do some testing with a razer blade. I had a Q6600 with a Thermalright Extreme 120, well to start with both surfaces were very concave, so I decided to lap it, didnt regret it once after, because after doing 400-2500 grits, I got a 11c drop in temp for doing both surfaces in Prime95 Small ffts, just awsome!:rocker:
 
Makes on average 8c difference on loads temps for me. I now lap all of my intel CPU's. Idle temps arn't effected too much, maybe a couple of degrees max. Unless you are going for maximum overclocks and you obviously have a warped IHS (which most are to some extent due to the solder on the core) then I wouldn't bother, however if you are a perfectionist then it's most definately worth it. I wouldn't worry about voiding the warranty as CPU's rarely fail unless you pump massive amount of volts through them in which case the warranty is void anyway.

See my avatar for a pic of my Q6600 :D
