Reducing the CPU temperature has always involved newer, larger heatsinks with ever more powerful fans. All of that mean extra costs. But what if you could have better cooling without the extra cost? For only $20 in sandpaper, you could reduce your CPU core temperature by 15%! So, join graysky as he shows you how to lap your CPU heatspreader and heatsink for a much better thermal contact and better cooling performance. Here's a quote from the guide :- Link : The CPU & Heatsink Lapping Guide
Hehe.. I don't think it's the CPU now. I tried it with a different CPU... and graphics card. Still no go. I just stripped it out of the case. Will be testing the parts one at a time until I find the cause.
Why so concerned about a HSF warranty, of all things...if it so happens that the fan dies, you replace it. Simple Nothing else about it is going to wear out.
Hehe.. I think his biggest worry is voiding the CPU warranty. Then again, CPUs rarely die.... unless you mess around with it.
