Hey everyone. Sorry for yet another post in the forums like this, but I'm stumped as to what to do. My 6400+ BE is running in the mid to high 40s idle and high 50s to low 60s while gaming (using CoreTemp). At first I used an AMD HSF from an X2 6000 a friend gave me (the copper pipe one) with Antec Silver compound. Thought that might be the problem, so I got an Arctic Cooling Freezer 64 Pro. Almost exactly the same temps using the pre-applied compound. Keepin the side panel off only drops it about 5 degrees celsius. Here's the specs:

X2 6400+ Black Edition with Arctic Cooling Freezer 64 Pro
4GB Crucial Ballistix DDR2 800 RAM
Gigabyte GA-M59SLI S5 with latest BIOS (version F8)
250GB Maxtor SATA HD
Nvidia 8800 GTX
Antec 500W PS
Five year old Antec mid tower case with two 120mm fans (front and back)

I've doubled check all fans/heatsink to make sure they were spinning and in the right direction. It's in a cool room I called AMD and he said the top temperatures while gaming were almost at the max recommended (63 C), but he said it wouldn't be dangerous until it hit the high 60s or 70 for long periods. He also said the mobo just may not be reading the temperature correctly.

I would think it was the case, except it drops so little while open. I'm also sure I'm applying the silver compound and heatsinks correctly (snug fit , no compound in the socket). It's been stable like this for two months now, but it's still a nagging question for me. Is there anything more I can try? Thanks for you time!

With a 5*C drop in temps when opening the case I' d look at case ventilation first. Try using higher capacity fans for exhaust and intake.

Well, I took the easy route. My case has two brand new Scythe 120mm fans in addition to the new Arctic Cooling HSF. My only other option there is to get another case, which I'm not ready to do just yet (maybe a new Antec 900 after the tax refund ). In the meantime I decreased the voltage on it from the stock 1.4 to 1.3. I've been playing Oblivion all day and it has been staying at 56C to 59C under load with no stability problems (which is about a 4-5 degree drop from the stock voltage). It's at a safe range now and should do me until I can afford a new case. I do think you're right, this five year old case, while very nice looking, just wasn't made for the heat generated by today's gear from an air flow perspective. Time to finally upgrade that.
