Weird temp. risings

[JaaP]

Hello all,

I have a
P6N SLI Platinum
E6300
Artic Freezer 7 Pro
HD2900XT

I just have the 2900XT for a week now and since i have installed it my CPU gets way to hot. (i think)
I had it at 2.7 ghz and temps got to 68Cmax in TAT. idle it would have been around 48C.
Now since i have installed the card and a new PSU the temps are idle around 52C and ive seen it hit 70C max in TAT (!) :S witch i think is way to high. I had to remove the Freezer 2 times to install the PSU and i havent placed new Cooling paste (don't have it, thought it wouldnt be necessary)
Could it be that i have to place new cooling paste or is the 2900XT just rising up the temps in my case??

oh yeah forgot to mention,

I now have everything clocked back to normal (1.8Ghz) to see what happens to the temps.....now its idle around 47C witch doesnt even make that much of a difference.....what should i do???

I have a Antec SLK2700BQE with 2 huge casefans, one in the front and one at the back

what was the temps before you installed the 2900

the 2900 gives off a fair amount of heat but just incase i would double check the seating of the HS you may have nudged something when installing the 2900

I had it at 2.7 ghz and temps got to 68Cmax in TAT. idle it would have been around 48C.

And i believe before i started clocking the temps were idle around ~40 degrees
I am almost certain i havent bumped anything when placing the cooler back, i have done that with a friend of mine and we were very careful....

You need to clean off the old thermal grease and replace with new. Theat should lower the temps.

Ok i have just ordered some Artic Silver 5 paste so i will apply that monday. In the meanwhile i have clocked my CPU to 2.45 Ghz @ 1.100 Volts, NB @ 1,3 Volts. Idle the temps again were around the 52C.

I have removed the side of my case and now temps are 45C idle and it gets to 63C max in TAT!! I think that would mean that i have a worthless airflow but i cant place any more casefans!!!

If you continue to use the PC set everything at stock for now. Your load temps are at the VERY HIGH range.

Ok, now that bad airflow is established as a problem, if you can remove one of the PCI slot blades next to the video card, a PCI slot case cooler is made could solve your problem. New Egg has one, the "AOC FC-2000 PCI slot Case Cooler" and it costs only $4.99, so it isn't a high cost even if it doesn't work.
