Q9550 running hot

Hi,

My q9550 chip is running really hot. I'm using an after market heat-sink, also. ( http://www.newegg.com/Product/Product.aspx?Item=N82E168... )

It seems to run at the same temps on any vcore setting. At 1.2 volts it runs at ~45 idle and up to 70 on load. It runs exactly the same at 1.35, where it can be OC'd to 4ghz stable.

I replaced the heat stink a few times, and I just replaced the thermal paste but it hasn't helped. It's just gotten really quite warm in my area (90 F, a little humid) but it was still running hot before that.

Any ideas?

Odd you get the same temps on 1.35 vs 1.2...

Your temps don't seem TOO bad, especially for the overclocked temps.

I'm at 1.26 and I idle around 35c and load 50-55c. My ambients however are 22c (70F) compared to your 32c (90F).

If you have reseated and reapplied thermal compound there isn't much more you can do other than replace the heatsink. Out of curiosity what were your temps on stock cooling? If you ever had it on.

And I'm using http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I never put on the stock heatstink.

I just reapplied thermal and remounted the heatstink again and I'm idling now at 39, 44, 42, 39. So I may have dropped a few degrees.. it may go down a bit further when the thermal paste gets situated?

I spiked to 72 degrees while playing a game and it worries me a bit. My ambient temps will frequently be like this as my family is too cheap!!! hehe. I mean, I want the chip to last at least 2-3 years..!

Anyone have any ideas why the temp won't change with a low vcore? Is the ambient temp just too much to handle?

I pull the board to replace Intel heat sinks. It assures proper seating of the pins. I also "stagger" pin insertion.... ie: opposite corners vs doing it in a clock wise manner. This ensures a more uniform contact.
I also use Thermaltake Duorb's. ( there are some boards these won't work on.... XFX for one because of a large capacitor ). Best for the job and don't warp your board like Zalmans and are much quieter than the one you're using. My 9550 runs at 37c under true load.
