Temp on Opty 175 (939) too high!!

Mang0 Tree · 6 Apr 2007 at 13:22

Hi

I have a Opty 175 and I'm having problems with the temp being too high. The processor is running at stock, with AC Pro fan.

It's housed inside a Pratorian Aluminium case, with 4 x 80mm fans running, At full load, the temp is around 60C!!

I also have 2 x HD, 2 x DVD, a 1900XT and a X-Fi soundcard installed.

At first, I though the CPU was not seated properly, but I have reseated it 4 times, temp is always around the 60c mark every time I reboot.

I have used MX1 and AS5 paste, with no difference in temp.

Can you suggest anything other things I can try in order to get the temp down...

Thanks

Wow - my 165 only ever got close to that @ 2.95!

Check the seating on the Freezer Pro - some people have had problems with clipping them on correctly! They sometimes simply don't contact the core properly.

If you have the stock cooler (the 175 should have come with the fancy stock heatpipe version which is very highly regarded) then try fitting that fella!

My 165 ran hot and that tended to be a side effect with some steppings. Yours may be the same but i'd say it was an extreme example if it is!

Has it ever run cool or is it newly installed?

That is very hot, for a 175 at stock. Even with the standard hsf, you should'nt be seeing temps much above the mid 30's at idle and mid to late 40's at load. As has been suggested, try the stock hsf and see if your temps improve. If they do then it suggests a problem with the way your Freezer Pro is mounted.

might be a badly seated IHS... you might want to remove it and apply some thermal paste. Re apply it.

WARNING... this is dangerous and you might destroy your CPU.

If I remember correctly the AC Pro fan was no better than the stock AMD Heatpipe HSF, those temps look similar to what I was getting with my opty 180 at full load 58-60c

Was that at stock Dutch or overclocked when you got those high temps?

Just updated above post - stock HSF Pic was overclocked by 200MHz, Zalman CNPS9500 was overclocked by 300MHz

Cool.

I think if Mang0's got the stock cooler then he'll be laughing.

Must be the Freezer Pro? Some of those do an awesome job while others just simply don't seem to work! :rolleyes:

Well guys, I've changed to the AMD one and it's not worked. In fact, the temp reading is even higher, it's now reading at 64C!!! :eek:

The idle temp with the AMD cooler is in the low 40s :confused:

jaykay · 6 Apr 2007 at 14:35

what software are u using to read the temp

Mang0 Tree · 6 Apr 2007 at 14:37

I'm using Core Temp as well as the one that came with the Asus board. The temp is read while running the SMP client for folding@home

gt_junkie · 6 Apr 2007 at 14:40

Must be a poor IHS contact.

Shouldn't be getting temps anywhere near that @ stock!

Should be more like mid to high 40's i would think.

What's the case/system temp and what's the HDD temps?

geeza · 6 Apr 2007 at 15:27

temps are for gays. my x2 3800 has been up to 83c and its fine

Holy melting silicone batman!!! :eek:

Wow... that must be clocked to 3.2ghz for those temps surely! That or you've got it running at 2ghz but with 1.9v going through it!

What cooler you using geeza?

The reading from PC Probe II show mobo temp at 37C. I'm not sure how accurate this is as the room is not exactly warm. The PC is sitting 12 inches from a wide open window :confused:

The HDD temps are usually reasonably accurate so I suggest you download NextSensor and it'll tell you your HDD temps and you'll then have a better idea about your case cooling being good or not. Is your AC Pro blowing the hot air towards the back case fan or towards the PSU. Blowing towards the back case fan usually results in good case/system temps.

Sometimes when I've fitted the AC Pro the idle/load temps have been terribly high even though it was definately fitted properly and I don't know what was wrong. It could be improper cleaning of the old thermal paste or too much or whatever. Anyway the last time I refitted one I cleaned it with isopropyl alcohol and put a grain of rice size on the heatsink only and used a bit of a clear plastic bag to smear it all over the heatsink as thinly as I could and the temps were great when I did that.

As a comparison I've an E6 stepping (Toledo) X2 4200+ running Orthos just now using an AC Pro and it idles around 31/32c and tops out at 53/56c. It's at 2.8GHz with 1.35v (stock volts).

Right, I have installed Netsensor and as far as I can tell, the reading are very similar to those taken by Coretemp and PC Probe.

There are no temp reading from HDD, but I have noticed Nextsensor is now giving me temp reading of the two cores plus processor temp.

It is saying the core temps are 58C and 63C while the processor temp is 44C, these are taken at full load.

Str, thanks for suggesting improper seating, improper cleaning etc of paste/CPU.

The thing is, I have now reseated the CPU about 10 times, every time the CPU is reseated, the thermal paste are cleaned off thoroughly using TIM Cleaner. The paste are applied using lint free lens cleaning tissues

I have used two different AC Pro, plus the stock AMD cooler, using MX1, AS5 and bog standard paste.

The result are the same every time, so I don't think the CPU is seating incorrectly.

I am tearing my hair out trying to figure out why the temp is so high!!!

str · 6 Apr 2007 at 16:37

What's the TCaseMax and TDP in CoreTemp?

When you ticked to enable the HDD temp sensors in NextSensor did it show the temps as 0.00? Would be strange as it's always worked for my HDDs.

Wouldn't the lint free tissues end up mixing in with the paste resulting in very bad thermal conduction?

Try cleaning again and put the CPU in the socket and put a grain of rice sized AC5 on the CPU but don't smear it etc just fit the heatsink and see what the temps are with that.

jaykay · 6 Apr 2007 at 16:44

as5 paste takes a while to seal this drops about 2-3c though so not enough

how much voltage is going through the 175
