| 238167 | 2004-05-22 07:51:00 | I am with Terry on this. Its all relative to the ambient temperature. The PC will run X degrees above ambient, where X is a variable dependent on the things like efficiency of the heatsink and CPU acivity. It will not (and cannot) run below the ambient unless its suddenly become a Peltier device. Stating CPU temperatures is totally meaningless unless you are also measuring and stating the ambient air temperature in the room, where the case gets its cooling air from. |

| 238168 | 2004-05-22 08:01:00 | well those figures I've posted showing what the system is running at right now are taken in a room which has had a roast cooked in it and heater goin most of the day.......is pretty warm in here........ah.......current cpu25 mobo29 ......fractional increase due to cooking i'd say.....still pretty cool tho..............I dont have an interior thermometer so I cant say what the room is at but cept that it's warm | drcspy (146) | ||

| 238170 | 2004-05-22 08:14:00 | And, at the risk of repeating myself from previous posts, the components used to measure temperatures on motherboard and CPU's are "a guide only" . They are 20 cent components with no calibration usually . Errors of 10 degrees could exist . A calibrated accurate temperature meter would cost as much as the motherboard, to put it in perspective . The on board sensors can be accurate, and more likely can be inaccurate . Unless you check the calibration with a known instrument, then the readings are purely speculative . My mobo temperature is at least 5 degrees out as an example, using a calibrated meter as a test . Its almost impossible to check the CPU sensor due to location . |

| 238171 | 2004-05-22 08:18:00 | I have CPU 49 deg C, mobo 43 in both Everest and MBM5, Winfast utility concurs with that. (AMD 2600xp,) and it is working moderately hard( with seti in the background to use anything the main apps leave spare) The outflow air feels pleasantly warm :) | R2x1 (4628) | ||
| 238172 | 2004-05-22 08:43:00 | A P4 runs cooler than an AMD... accepted, but it is all relative. A Pentium P4 2GHz takes a current of about 44 amps, and generates about 52 watts, at 2.4GHz it will be somewhat higher. It is a basic law of physics that to have a heat transfer there must be a temperature difference, ie heat travels from a hotter to a cooler environment. If the cpu temperature is about the same as the ambient temperature then there is no heat transfer, which would mean the cpu is turned off. If the cpu is running and dissipating about 50-60 watts into the heat sink, then with average heat sinks and fans the temperaure rise above ambient is going to be about 15deg C. By ambient I mean the air temperature that the fan is blowing across the heat sink. This may be already about 5deg C or more higher than the air temperature outside of the case, that is, 5deg C above room temperature. I would not "believe" any reported cpu temperature using 'normal' heatsinks and fans below about 35deg C in a room at about 20C, I would in fact expect somewhat higher than that. |

| 238173 | 2004-05-22 08:50:00 | My AMD 2200 is reporting a temperture of 24 degrees . . . . . . . . . . woohoo . . . . Except its so cold in here that my teeth are chattering and im having trouble with my bourben and coke . Only one cure for that,more bourben,less coke* *Expect the quality of my posts to plummet even futher as the night goes on . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

| 238174 | 2004-05-22 09:01:00 | So your room temperature is down to about 8C Metla, no wonder you are cold :) Talk about masochism, if you're not careful your cpu will start suffering from hypothermia, alcohol and cold dont mix. In the event of hypothermia it is important to raise the core temperature, the best way of doing this is to give your cpu a good hot drink. |

| 238175 | 2004-05-23 03:12:00 | Bourbon (or any alcohol) is a vasodilator and actually increases your body heat loss, until the core temperature reduction starts to shut things down . The booze just makes you feel better as you freeze to death . But you can believe it when your AMD 2200 reports a "temperature of 24 degrees" . Everything that comes out of a computer is correct . And if you believe that, I have a number of deals "too good to be true" for you to invest in . :D |
