My X2 4800+ has high temp jumps at max load help.

I still have one of those bend out panels on one of my PCI slots on my case just under the GPU, so I've bent the panel so it's now angled towards the exhaust of the GPU and it seems to have made the CPU max temp drop by 3 degrees.

I did this because I noticed the panel was getting nearly too hot to touch so the air from the GPU was blowning against the back of the case then all around the rest of the case before getting to the exhaust.

A aftermarket GPU cooler would definitley help as a AC X2 cooler drops the temps on a X1950pro by 10 degrees apparently but I'm not wanting to change the GPU cooler atm.

A couple of days or so and I'll have the 120mm fan and other parts to attach it to the front of my case, see what happens then.

That's what I was thinking. When your air flow is well optimized, you should get atleast comparable temperatures between your side panel on or off. Ideally, you would get better temperatures with your side panel on.

I do, but my video cards don't heat my systems up much. IMO, hot video cards are a problem area that require special attention to keep them from heating up your case. (i.e. a side panel fan blowing directly on them and removing any unused PCI expansion slot covers, side panel fan with GPU cooler that exhaust out the rear, etc)

I want to say that I was talking about generally, and not you in particular obviously.
I agree with you about the video cards. They can make your ambient temperature rise very quickly if the case is not well ventilated.
I'm curious, what is your case Widjaja?
I'm mostly suprised by the huge difference between both cores at full load.
I was talking with pandaman on MSN 1 or 2 days ago about your case and thinking it could have been an integrated heatspreader problem, like Lead Head mentionned earlier. There's no real way to cure this without voiding your processor warranty however if that's the case.
You said you apply thermal paste as in Arctic Silver instructions. I'm not going to imply you don't know how to read or anything, but are you sure you have carefully applied the thermal paste, so it makes an even contact between the processor and the heatsink?
Besides, that voltage is quite high only to get to 2.6Ghz, which could explain the overall high temps.

I'm glad I've never known my individual core temps, it would probably drive me crazy. But, keep in mind that unless both cores are running at 100%, which is nearly never, one will be hotter than the other. (100% usually means one core is actually at 100%, and the other is bouncing back and forth between 70% and 100%...at least on my X2 Toledo core...I spent many, many hours watching Power Monitor and A64Info with fascination)

as a bit of extra info, my cores do run at 100% 24/7... I run F@H

Never a 10 celsius difference on full load, really. At best a 4 to 5 celsius, even then it's most often around 2 celsius.

Same here. Between 40 and 45 celsius core temp at F@H SMP load, depending on the room temp (between 70F and 77F at time).

A 10*C delta between the cores like that either means you have either a poor mount, a badly shaped heatsink base / ihs, or your heatspreader has poor contact with the core itself

I was trying to remember if I ever ran F@H on my 4400 when I got the Q6600. It was always the program I used on single core rigs to check load temps. I don't think I did, I would have remembered if it maxed out the CPU.

The Quad runs at 22% with F@H. I pretty much never pause or quit...didn't even pause it while playing Crysis this weekend.

That's pretty much only 1 core being used, then. :P Cmon, get folding on the other cores!
And I never pause it either.
