Nasty heat problem

[pipsey]

I just built this system:

Soyo CK8 Dragon+
AMD Athlon 64 3400+
Aluminum case with 400W PSU (I know I should replace the PSU that came with the case, but that's for another day)
2GB DDR400
ASUS RADEON X800 256MB
Cooler Master Hyper 6 (Also tried the stock HSF)
10000RPM SATA150 36GB HDD
Pioneer 8x DVD+-RW

I was hoping for a kickass machine, and certainly it's good (and expensive), but the Soyo board automatically overclocks the processor by at least 200MHZ and won't let me turn it off! This would be great, if my CPU temp wasn't 80C under load. That obviously makes me nervous and I can't afford another 200something for the liquid cooling that would probably help (unless it's a last resort).

I'm wondering if this temperature reading is somehow incorrect seeing as most people with similar processor/HSF setups report much lower temperatures, and even though it is overclocking my 2.2ghz processor to a 2.4ghz processor, it shouldn't be THAT much higher...

Any suggestions as to what I could do with this? I'm somewhat afraid to leave it as is.

A 200MHz OC would not bring your CPU temps to 80 C. That's a lot hotter than my Prescott CPU. How are you monitoring your temps? Install MBM5 and see what temps it reports.

Touch the very base of the heatsink, if its really 80C then it will burn your fingers.

that heatsink is top knotch, it should obviously be a hell of a lot lower. the reviews say its extremely hard to mount due to its size. take it out and remount it and reapply thermal grease or material to make sure its installed properly.

I have touched the very base of the heatsink, and it's only slightly warmer than the case temperature.

My friend also built the same system (well with a better PSU than mine) and it runs similar temperatures (about 6 degrees cooler than mine because it's right next to the AC). I downloaded the SpeedFan program listed elsewhere on this site and it gives me these temperatures:

Temp: 39C
Temp1: 39C
Temp2: 80C
Temp3: -128C
HD0: 26C
HD1: 33C

MBM5 doesn't seem to be compatible with this motherboard, or at least it doesn't have prepackaged settings for it..

 

[AWhackWhiteBoy]

well this is tricky, it could really be 80C, and its not a good contact with the heatsink(hence it being cool), or the diode could be very wrong...

See if Soyo has a new BIOS flash. It could be that the Diode is totally off. However, check your thermal paste/heatsink placement just to be sure.

 

[pipsey]

I'm fairly certain it's in there correctly. As I said, similar results in two seperate installs by two different people, and also I tried the stock fan and got even higher temps (it was pushing 90!)...

Does anyone know where I can get something to make a Win98 boot CD that I can stick the bios upgrade on? I did manage to find a nice boot cd, but it's NT based (Win2000, NT, XP not supported by the bios flash program, great). However, my friend updated his bios, since he has a floppy, and the temps did not change.

The system doesn't seem to be going wonky during normal use.. I'm just worried that it'll get toasted when EverQuest 2 comes out and I try to play that on it..

I would check soyo's website first to be sure the latest bios flash will fix your temp readings, before flashing. It's not worth risking your bios chip just for the high temps. I would also recommend a power supply with the 12cm or 14cm side single fan. I use a sparkle 300w, and can still run my p4 at a 30% overclock. I had the same problem, but a bios flash didn't fix it. My temps were up to 84c; now they read 66 celcius max with the sparkle power supply. The sparkle is only $35 shipped at newegg. Super flower and coolmax also make good ones. Use the single fan models only. The multi-fans are too noisy.

 

[pipsey]

Well, that's a possibility, then.. this PSU is an Mwave that I pulled from another case. It IS a super flower case, but the PSU that shipped with it was dead so I replaced it with a spare. I didn't really consider whether a different PSU would help..

cpu cooler by thermaltake polo735 3in1 cooler with tt ducting mod installed.
mbm monitor and those other programs will read the temps the same if its 80+ in the bois the other programs will report that temp if the hsf is cool to the touch, provided its installed correctly, then it working fine and its a problem with the mb. If you want to be sure you should get a cheap temp monitor. onceyou get the thermal diode close enouugh the the cpu you can read the temp, i have one and its only off by 4 degrees when compared with the temp that the mb reads.
Check www.bootdisk.com to make a boot disk.

Sounds like there's just something wrong with your motherboard's sensors. In any case, *if* it gets too hot, the system will just reboot. Your cpu should be safe.

But if it doesn't feel like 80 degrees, then it probably isn't.

 

[Shimmishim]

you sure you have a 2.2 ghz clawhammer? and not a 2.4 ghz newcastle?

 

[pipsey]

Well, now that I look at it, it's a newcastle and isn't being overclocked, I guess, despite the way Soyo's BIOS reads. I bought the processor from MWave, and let's just say they are NOT very helpful with their descriptions (besides sending me a case with a dead PSU and a bad video card before that).

diode, diode.....if you can get you hands on a temp sensor with external readout you can slip the sensor into the base of the sink, but the touch is all telling here.....
