Default Zalman CNPS9500LED temps too damn high.

Okay, specs are all in sig, using Arctic silver 5.

Vcore set at 1.4 in BIOS, actual is ~1.35, CPU at 3.2ghz.

Temps just messing around in windows is 50C flat, games go to about 57C and Orthos around 65C. System is perfectly stable, but these temps just seemed f*cked to me. Ive tried reseating the heatsink, reapplying AS5. I'm not an idiot and Ive built rigs since I was 13, so it cant possibly be the way I'm mounting it. Does this heatsink just suck this bad? I'd much rather see it idling at 40 and orthos at 55.

Using coretemp btw. TAT corresponds with coretemp so i just use coretemp. BIOS reads it as like 75C from a coldboot. Does this seem screwed to anyone else?

I have this feeling coretemp, TAT and my BIOS are all lying to me. The heatsink isn't even hot, isnt even warm. I swear to god im gonna throw this sh*t out the window. TELL ME THE TRUTH YOU MOTHE...

Dont know tbh,my system wont overclock to that level,at default my cpu temp is 32c idle.@2.8ghz its around 37-38 idle but thats as far as ive gone without bsod/registry errors.I'm using the same heatsink and as5 but also 4x120mm fans,2xinlet 2 x exhuast plus a 40mm 5000rpm fan on the nb.

I have the same cooler without the LED, same cpu. My Idle temps are right now 47c at 3.4ghz and roughly 1.4v (I don't got pc probe installed atm).

My idle temps a month ago where around 42c. The weather is getting warmer which means my temps are getting warmer too.

Too much AS5 maby?

I have a theory, i just noticed the alcohol i used to clean the cpu and heatsink surfaces is only 70%, i just picked up some 91% from CVS so im gonna try reseating it with that and I'll report back to u guys.

Yeah so that didnt make a damn bit of difference.
My computer is laughing at me right now, I can tell. It thinks this is funny. Oh well, 50C in windows it is.

At 55C the heatsink should be getting warm to the touch if it is drawing heat from the processor. The base of the heatsink should be reading almost 55C.
Make sure you are getting good contact on the heatsink's base with the core.

Yeah i thought the same thing. But theres really only one way to mount it and as far as I can tell im getting good contact. When i took off the heatsink to remount it there was AS5 on the base of the heatsink itself so I suppose its getting good contact.

I've seen smaller, very light push pin hsf's that I've heard are superior to the zalmans and they look like it too. Check out performance pcs. They might have something better.

Also, when you apply the as5, i've thought it was best to spread it, a small amount so there's no air pockets.

Also, make sure you're using the latest bios, if you aren't already.

Also, maybe the 9700 zalmans are more suitable for the core2 duo, but I'm not sure.

I also think there's some kind of voltage setting that may be causing it to run hot.

Finally, I think the Ultra performance model Panaflos are good, you can buy those from performance-pcs, but I've heard a rude guy answers the phone, but I've never called them, and whenever I've ordered everything's been perfect.

I guessing it is lying myself. I've had one gigabyte board that I knew was wrong because it was reporting that the FX-60 in it was going over 80C, but the fan wasn't even kicking on full blast.

I was running 48C loaded with the FX-60 @ 2.8 1.5V, that was on the 9500 in the DFI board.

Actually, there are only a few coolers that can even best the Zalman, and they have a lot more metal on them. I'll have to find the link but it was an Anandtech article. EDIT: http://www.anandtech.com/casecooling...spx?i=2943&p=3

According to what I've heard, all you need to do to make AS5 work is put a BB sized drop in the center and smash it down, it will spread under the weight of the cooler. I personally prefer to spread it out with a razor blade, and haven't had any problems like that.

I've seen what might be a defect. It might be concave, instead of flat (the base)
