Worth it?
i currently get about 85oC on full load for about 30mins
with my spec in my sig

iv got push/pull going on the TRUE with cheap 2000rpm fans

was thinkin of getting scythe slipstream fans for there high cfm output

lapping the cpu and TRUE

new thermal material, ocz freeze instead of thermalrigh chilli factor

hoping for 5-10oC drop

or is that too ambitious?
 
that seems do-able getting a cpu with better fans you will proberly drop about 5oC and lapping both heat sink and cpu ive seen people drop up too 13oC so i wouls say its worth it iam about too do my q6600 when my mobo gets back from being RMA'ed :(
 
check the contact you have got with the thermal paste and the die. If you are having to put too much thermal paste on to get a good contact, then its time to lap either the cpu or heatsink. Probs best to lap the hs first to avoid voiding the warranty on ur chip
 
Not always a good approach that ^.

Heatsinks are often deliberately shaped to get better contact. When screwed down, the base flexes. So the base may well be bowed, so that it goes flat under the applied force. This is especially true of waterblocks. It may also be slightly concave, to match the slightly convex processor surface. If you lap both, you're definitely onto a winner. If you only lap one, it might make a difference, might do nothing, might make things worse.

That said, the TRUE is not well known as being very flat, and lapping mine got me about 5 degrees. It took a long time with a lapping machine, so be aware that lapping a true is going to take you quite a lot of patience. Still, I'm glad I did. Lapped my processor too, who needs warranties.

In *this case* I strongly recommend lapping the TRUE, but others reading should be aware that other coolers may function worse when lapped. When in doubt, lapping both is always good.

Not heard much about ocz freeze. AS5 or MX2 are the favourites. I strongly suspect liquid metal to be much better than either but have not used it yet, I will do on my next build.
 
dont lap it

it makes hardly any difference
i would lap the cooler

then get some decent HIGH CFM fans

try some YATE LOON 120mm - D12SM-12

an i7 dumps heat quicker than most coolers can handle

i would suggest dropping your clock/volts

as the last i7 i clocked on a TRUE went to 4GHz [D0 stepping] whilst staying under 75'C

with two noctua NF-P12 fans in pushpull
 
i lapped the cpu and true and changed my tim to ocz freeze

im topping out at 72oC

didn't lap to a mirror finish but worked it down a lot

worked up to 1200grit don't think i would get much more going up to say 2000 grit

worked on it for 3 hours what a work!

arms are aching but content with the new differences.

gonna get the scythe slipstream fans in the near future hopefully they'll reduce temps a little bit more :]
 
You could always accept that 4.0 is just going to be hot on air and bring it down to the 3.8.

I could hit 4.0 and get the exact same temps as you but was not happy with those temps so went back down to 3.8.

Other than that there is always water but I honestly cannot tell one single little shred of bit of difference from 3.8-4.0, especially on an i7.

Oh wait, I forgot about the shrinkage of your e-penis... other than that, can't tell a difference no matter what I'm doing.

yeah i do a lot of rendering so the more processing power i have the better!

i feel that 72oC hottest is fine! considering it doesn't throttle at all and probably won't until 95-100oC cus it never throttled before!

im just gonna stick with 4Ghz, can't wait for GULFTOWN rendering will get a boot in the ass when that comes out :D
