Solved need some help please

ok i got a new (Q9550) chip and started overclocking it . i started out with 400 x 8.5 and voltage 1.12 everything went fine .tested it with prim95 for 12 hours no errors and highest temp was 72c. so i moved it up to 450 x 8.0 (3.6ghz) same voltage and
tested for 12 hours no errors and temps still at 72c.so moved it to 465 x 8.0 same thing 12 hours no errors and temps 74c. went to 480 x 8.0 and voltage 1.18 it tested fine for about 4 hours then the temp went up to 95c.i stoped the test as soon as i seen it but why is there so much more heat just by moving the voltage that little? could it be because maybe the chip is working harder do to the low voltage?
thanks scrooge

Well, the higher you push you frequency, the harder the processor works and more the more it requires higher voltage! Thus more heat! This is a normal by product of pushing the processor to work harder.

You're now getting into an area where more/better cooling is required to keep the temps low for said frequency. In short, if you want to go higher, get a better cooling solution.

i have a after market heahsink/fan on the the system but i guess i'll have to go for something else.
any help ?

Research and money. Plus how high are you trying to go? Is air enough, or do you want water cooling.

From all that I've read and heard - this is tops in air cooling - Newegg.com - Noctua NH-D14 120mm & 140mm SSO CPU Cooler. But it’s big, heavy, and expensive.

I have this - Newegg.com - Noctua NH-C12P SE14 140mm SSO CPU Cooler - But I wouldn’t recommend it for clocks going near or past 4gig.

See my post here concerning clearence with the SE14 - http://www.sevenforums.com/hardware-devices/81169-experience-gigabyte-motherboards-3.html#post775794
