Could you more condescending? I doubt if this person has posted 10B questions.

205226 2004-01-04 21:02:00 I would put a correctly set up amd at 30-50 degress,That is to say everyone i have assembled has fallen within these tempertures,If the cpu is running at 66 degress at idle then it needs to be looked at.

And i hear the sensor on intel sockets is in the corner where the temp is lower then in the core,But amd probally do the same,or it might all be complete bollucks.

I don't supose someone running a 2ghz or over P4 cpu running a stock cooler could post a temp reading?

205229 2004-01-04 23:18:00 My 2200+ is running at 34 degress,stock fan and heatsink,no case fans,In a stuffy hot as hell room with no ventilation. metla (154)
205230 2004-01-04 23:20:00 I didn't install the heatsink myself. Iv'e got one fan. I removed the case and placed an air-conditioner next it for a while. the temperature dropped significantly.
the little hardware sensors moniter program told me that the temperatures weren't in the red zone.

Must be underclocked or the sensor is misrepresenting the actual temp? That is awfully low for a closed in case with standard heatsink in a hot stuffy room. My bet is that the temp inside the case is not far off 34 deg, let alone the heatsink. Pop a thermometer in there and see?

In my hot stuffy office at the rear of my garage, Aida reports:

Temperatures
Motherboard 29 °C (84 °F)
CPU 59 °C (138 °F)
Aux 35 °C (95 °F)

Motherboard
CPU Type AMD Athlon XP, 2079 MHz (6.25 x 333) 2600+
Motherboard Name Gigabyte GA-7N400-L (5 PCI, 1 AGP, 4 DIMM, Audio, LAN)

I can't get MBM to report accurate values for my CPU sensor ... either sits on 30 degs or over 80!

AMD say that thermal paste is not a long term heat transfer agent and push the use of the tape that is stuck on their heatsinks. What are your recommendations?

205232 2004-01-05 04:24:00 Well,Due to the widely known inacurecy of the sensors and seeing as i dont have a thermometer i must of course entertain the notion that im getting a false reading.

Just done some video encoding while monitoring the temp,and while it flucuated wildly seemed to sit around 46 degress

Just checked my other system(xp2000) and shes reporting a mid 30's temp at idle as well.

And also fired up my 3rd system(duron 1100) and thats giving a reading of 28 degrees.

And of all the systems ive built all give much the same readings when they go out the door.

As for the heat tape,first thing i do is scrape that poo off,then rub some thermal compound directly into the heatsink,then polish off the excess,then put a thin even amount on the cpu where it makes contact.

My gunk of choice is Artic alumina ceramic thermal compound.

Still,I supose it wouldn't hurt to get a real reading.

Anyone know of a thermometer built specificly for reading cpu temps?

205233 2004-01-05 07:39:00 I may have to look at getting some paste and removing the tape. I have always been wary of the tape but reading the AMD site and watching their how to mpegs they stress that the tape is preferred over paste. I didn't want to validate the warranty.

Thanks Metla :)

205234 2004-01-05 08:34:00 I think there is a lot of non-tested, non-scientifically confirmed mumbo jumbo over the various pastes etc versus the soft pads as fitted to AMD heatsinks.
If such a heatsink is removed after some use, it will be seen that the combination of heat and the high force loading of the AMD heatsink clips compresses/melts the pad to microscopic thickness, so thin that the metal of the cpu can be seen, the surplus is extruded out at the edges.

Under such conditions simple heat transfer theory will show that the residual film is virtually isothermal, and presents very little impedance to heat flow.

Obviously if the heatsink is removed for any reason, then a new heat-transfer paste must be applied as thinly as possible after the residual
soft pad has been completely removed.
In addition if you want to be really keen, then it is a good idea to lap the heatsink really flat on a grade A lapping plate, ie flat to within a few light-bands of light :) no, seriously.

Once again it cannot be stressed more that to keep cpu temperature down the air flow through the case and to the cpu fan must be unrestricted. A forced draft at room temperature directly onto the cpu fan, ie like a booster pump in hydraulics is the sure fire method of minimising cpu temperature.
