AMD 1.2 with original Fan

[RP]

Hi
I have installed a new 1.2 ghz AMD cpu with it's original fan and heat sink.
The temp is 68 degrees celcuis all the time !!! is this normal ???
Help !!!
thanx

68 degrees is far too high for a standard setup like that. I would try removing the thermal pad and replacing with Arctic Silver II, and make sure you have total contact between the HSF and the cpu. Have you checked to make sure the fan is working?

No such thing as an original fan as evey amufacturer and shop fit the crappiest ones they have instock to save on money... go get yourself GlobalWins new one.

Get rid of that HSF ASAP cos u R gonna cause some serious damage to the CPU 68c is way too high.Try and get a FOP32 or FOP38 if U can stand the noise.

[Sohryu Asuka Langley]

is that a thermo engine gerti? if it is.. change teh fan.. even if you have to ditially do it.. hehehe

[Gerti]

Yeah thinking about that I might really try it if I get a pic of the delta black label.And by the way do U think I should change the stock fan on my Tengine to a
Ys-tech or a delta BL.My temps @960 are 41C idle and 45 under load at 1.85V(actually MBM and bios show 1.94V)

Am running a tb1200 at 1450 with FOP32 (highly polished and silver paste). After full Sisoft and Wintune benchmarks the temp is only 39.7C..case open though and room temp down to 18C. Have ordered a Swiftech m462 but that's a while away...As mentioned above you NEED some better cooling or you are liable to cause some electron migration caused thru heat and good bye little tbird...

Yup... get a better HSF, lap it, and then use arctic silver... it works wonders for stability :)
I've got an Alpha, and i love it...

"Highly Polished" Did did you buff it yourself? I heard from articsilver.com that should even mess with the bottom of a heatsink let alone Polish it. They said it reducess its performence by quite a bit. Well, I hope your talking about it comming factory polished.

Instead of getting a new HSF, you may just want to get the Delta fan (if you can stand the jet engine noise) and replace the stock fan with the Delta's. The heatsink itself is okay. It's the fan that isn't doing its job too good.

Anyway, I found it out about stock HSF that comes with retail AMD CPUs, if you get rid of the thermal pad (that pinkish thing at the bottom of the HSF) and clean it thoroughly and use artic silver on it, you will lower the temp by at least 10-15 degrees.

Good luck and don't fry your CPU!

U need an Alpha Pal6035 !!

Tbird 1200@1470 (140*10,5)
Abit KT7a
Alpha Pal6035
256mb pc133
Geforce 2 GTS pro 64mb ddr

CPU Temps :
-idle > 32°C
-full load > 46°C (after 5 hours of gaming and case closed)

By Polishing I mean I got all the imperfections (ie grooves and scratches) off the bottom of the heatsink where it contacts the cpu...the FOP32 had a lot of ridges and "scratches"..new

Ideally we shouldn't need and heat grease at all because two perfectly smooth surfaces would transfer the heat a lot better...but we live in an imperfect world....and the smoother we can get the surfaces..so no air trapped and as much surface to surface contact is made, the better the cooling results....my temps dropped by over 3C after polishing the hsf base...I dunno who advised you otherwise but they are way off the mark...maybe they don't want you mucking around with the hsf because you may damage the chip or something during the removal/reinstallation...and that is a possibility if you are not careful...but the benefits of lapping/polishing are well proven and scientifically supported by thermodynamic principles of heat transfer...the more direct contact..the better the heat transfer...that's why the sparing use of heat grease is essential...its only there to fill any minute air gaps caused by imperfections in the surfaces.

Have a look at the articles at http://www.burningissues.co.uk they are superb on all sorts of cooling issues.

I used wet and dry paper then used "brasso" to get a mirror finish. I then thoroughly cleaned them with alcohol and spread the silver paste VERY thinly with a credit card.

Attached are some pics showing the cpu temp after full benchmarking at 1450.

Have Fun
