how much does lapping help temps

post #1 of 10
Thread Starter 
i've got a Q6600 and wondering how much my temps would change if i lapped. right now i get 63C on prime small fft's.

also is there any way to tell the vid on a processor before you buy it, like say from microcenter?

Depends, sometimes if the ihs is pretty bad in terms of concave then it can help a good bit by like 5*c give or take and sometimes it might only drop like 1-2*c.

Not sure about the vid but I know I haven't been able to find out before I buy. Even if it is the same batch the vid can still be different.

Theres no way to tell the VID from the box as far as I know . Its a lottery and besides, a low VID doesn't guarantee a good overclocker.
Lapping helped my temps about 7*C off Load (78*C to 71*C) and 6*C off Idle temps (53*C to 47*C). But you lose your warranty and you must be careful not to get copper dust or water inside the CPU. Its simple but boring. You must really lap both the HSF and CPU IHS to get the best drop in temps.

My IHS was VERY uneven, and temps were a serious problem for me - Come to think of it, so was my HSF.

63C? that seems pretty hot. My D 805 runs at 51C with one of the cores loaded by Prime.

It depends on how flat the processor and heatsink are. I saw almost a 10c drop after I lapped both CPU and heatsink as well as making a bold kit to bolt the heatsink down for more pressure. Right now, with ambient of 28.2 im between 48-51c folding.

I went from unlapped stock clocked Q6600, Thermaltake Big Typhoon, and generic silver paste to

unlapped overclocked Q6600, TRUE lapped to a mirror finish, arctic silver 5 and...

my idle temps dropped roughly 12c and my load temps dropped 15c
