phenom 9850 temps too high! WHAT AM I DOING WRONG?!?!

post #1 of 14
Thread Starter 
Speedfan and CoreTemp are reporting 50-52C idle. I haven't tested CPU at full load yet.

I've used a Zalman CNPS9500A and Thermaltake Blue Orb II cpu coolers on this chip, both using Arctic Silver 5. The chip still idles at around 50C.

I can't figure out why! My video card idles at around 50C (9800 GT) so I don't think its a over heating issue with the case.

At first I thought it could be the mobo feeding too much voltage, but this motherboard does not allow me to reduce the voltage -- only increase, or Auto.

Speedfan reports a 1.28 Vcore. What can I do to reduce these temps?

How much thermal paste did you use? To much could case crap temps.

The Phenom is a hot-running chip to begin with...


That being said...your coolers aren't exactly known for stellar performance. Ultimately, you should get something better. Xigmatek and Thermalright both have coolers that will do the trick.


For making your current ones work, try cleaning the processor, leaving paste on the cooler, then trying again. Too bad your mobo fails too hard to undervolt...

Indeed. I just cleaned off a ton of goop from my GPU, no wonder it was idling so hot...

If you've got too much paste on there, clean it off (isopropyl alcohol and a q-tip work fine, if you have the fancy Arcticlean, great, use that), plop a rice grain-sized in the center of the CPU, and spread it out with the edge of an old credit card or something.

ChrisB17 and TestECull are both right. i would check the amount of thermal paste. i would not strip it all off. i would just remove the paste from the heat sink.
if you are planning on getting a new cooler get an wiggy s1823. the s963 works good but im loading at 53c with vcore at 1.4 with an 38mm fan with 120cfms.

As the others have said, it's probably the thermal paste. Also, the 9500 is generally better suited to dual cores, while the 9700 (and the bigger fan) do quads fine.

Alright, I'll try it. Thanks

Also -- I chose the the Blue Orb cooler because it is the only decent cooler that will fit in my case. Note, from my sig, that I use a SFF case - Silverstone Sugo 2 Black. It is very small; maybe a bit larger than a Shuttle XPC computer.

Thanks for the help! Appreciate it. It's driving me nuts and I never would have thought it to be the thermal paste. I do remember putting quite a bit more than just a rice grain...

That could be a problem then.

Thermal paste is really only used to fill in the tiny crevices on both the processor and heatsink base. If both surfaces were perfectly lapped, there would be no need for thermal paste.

Too much paste, and it acts as an insulator instead of transferring the heat.

It helped a little - idle temps are at 49-50C now...so it dropped a few degrees.

After break-in it might drop a little more.

At full load it hits 60-61C.

I checked and double checked everything...cleaned the heatsink and cpu entirely with rubbing alcohol...I referenced the 'grain of rice' when applying the thermal grease...spread the grease over the entire cpu heatspreader evenly using the business card of some real estate agent...turned the fans up to 100% (the blue orb 120mm fan running at 1600 RPM).

What else can I check to reduce these temps. The case is a little cramped so I'm gona try to clean up as many wires as I can.

Technically, those temps are fine now

I wouldn't be too comfortable with them though.

See if you can buy a better cooler

I recommend the Sunbeam Core Contact freezer
It comes with a full tube of thermal paste, a fan controller, and is a very good cooler for the price even if it didn't come with that stuff

(Before anyone comments about the "loose mounting mechanism", that doesn't apply for AMD. The Core contact freezer uses the stock AMD mounting method)
