Help. I just SLI'd my machine and it went from "hot" (40-48C) to "hotter" (50-65C).

I have stock AMD retail box combo fan, big sucka. I've read conflicting BS about "best" HSF. I'll take one that might not be 'best' but is rock solid good and no controversy.

I have checked the heat sink when running. It's pretty warm; I can touch it but it's not like it's boiling water temps. At 65C SS2 tends to crash. I ran the monitor and logged temps and it's just unstable when the temps get reported above 60-65 for a length of time.

I've got a front-to-back airflow with a bottom-to-back PSU fan config too. It's as good of airflow as you can have and still have a case ;-) Maybe I should just keep the side open all the time... Actually I've got 2 fans pulling into the rear, two pushing from the front, extra holes in the bottom of the case with a fan under the SLI cards...

Well, as good as your airflow is, you should probably expect your temps to go up a little when you add another heat source as big a 7800GTX. That's two video cards running at 55-65C at load, which will make it even harder for your exhaust system to remove all the heat.

I would recommend either getting a more powerful exhaust fan(s) or removing the side of the case whenever you want to do intense gaming.

Or, as you suggested, you could get a better CPU HSF.

Hope all this helps.

I suggest the Arctic Cooling Freezer 64 Pro for a good, cheap HSF. It runs under $40 and it doesn't weigh alot but cools very well. Also get you some Arctic Silver 5 thermal grease and you should see a considerable drop in your CPU temps. If your case has more room for fans I would add some. You may want to get some higher CFM fans for the intake and exhaust to help move the air in the case and get rid of the warmer air faster.
