Thermal Compound Question

Specs: Windows 7
Over the past few days my computer has been
overheating a lot. So I checked the idle
temperature and it was getting to about 85 in

Today I removed the old thermal compound
and put on arctic silver 5. Now when Idle, the
temperatures drop down to almost 60 Celsius,
but when I go to play a game on my computer
the temperatures rise to nearly 100 degrees
celsius within a minute.

When I was applying the thermal compound I
just spread it around all over the CPU because
I wasn't sure exactly what to do.

Edit: When I add pressure to the CPU fan it keeps the cores at about 70 degrees constantly even while a game is up, but as soon as I lift my hand the temperatures rise again.

Yes, you probably do need to reapply. Instructions begin here...

after re applying thermal compound, my computer idles at the
start screen at 62-65 celsius on all cores, but after 1 minute of
having a game window open my highest core temperature was
already at 100 degrees celsius. This is all with the case open.

Did you reinstall the paste properly? We have no idea which CPU you have so none of us can explain the right way to do it, but if you used more paste than approx size of a grain of rice, you used too much. And you should NOT spread it around, you either need to use the "dot method" or the "line method". Both surfaces have to be absolutely clean before you apply the paste & you have to make 100% sure the heatsink is locked securely in place. You should be shooting for idle temps under 40C (depending on room temp) with the case closed.

Yes I did. on the website it said to make a line across the CPU
so thats what I did. I tried adding pressure to the fan as it was
running and it kept temperatures from 70-80 even while playing a
game. When i relieve the pressure, temperatures go way up.

btw, my CPU is a Intel Core 2 Quad Q8200
the fan I'm using is the stock one that comes with the CPU and it's only running at 2400 RPMs

If the temperature changes with pressure either the heat sink is
misaligned or the retaining hardware is damaged.
