what is lapped? or lapping? - Page 2

post #11 of 23
You can also take off your IHS, the big metal cover that covers the CPU core. That will do more than just lapping to reduce your temps. But if you're new to this you probably shouldn't just "do it".

yeah i don't think i will, if i just get a good thermal paste, wont that be pretty beneficial compared to the sticky stuff that came on the HSF?

Yup! Arctic Silver 5! Also can be found at your local Radio Shack. This will drop 4-5C from the stock paste if added correctly.

Make sure you just use a tiny bit of AS5, like a rice sized drop. Too much and you will make the temp higher

There are several lapping guides and logs around these parts. If you care to take a peek there is one in my sig.

Understand that lapping your CPU will VOID ANY WARRANTY that you might have.

The results are real and tangible, but unless you really need to I wouldn't.

Also, you could start by lapping the HSF and see what kind of results you get. If you are not pleased and with to take it a step further, then lap the IHS. ...If you are still not pleased then you could remove the IHS.

Not really. I have been using the 1/2 rice size of AS5 for 2 months and just last night, I replaced it and added a thin line down where the core is at on my CPU. My temps dropped 4C idle and load. In my conclusion, the rice size droplet in the middle of the CPU was insufficient.

EDIT: I forgot to say, not the same method can be used on a different CPU. They all vary.

same process happens with CPU heatsinks as well

Check the attachment for AS5 pics. Just make sure you you press the HSF on the AS5 and maybe twist it a bit to spead the AS5. The AS5 will thin out itself and form a nice and thin film over the CPU.
