AMD tempetature - too hot?

The program is right, especially if lots of other people report the same temp with a P4, im not talking about an Athlon here. Look around other forums and you will see that P4's run @ lower temps. Thats all there is to it ;)

it is physically impossible to cool ANYTHING (a CPU) cooler than the surrounding air Your system temp is 21C/30C while you CPU is 36C.

by your theory, i could drive down the interstate on a warm day with a cup of water out the windows at 85mph and it would turn to ice

My power supply is 36*c, since if i put my hand in front of the outtake, I can feel really hot air coming out, and I have measured the temp at around that with a thermometre. If I feel the air coming out of the case fan, it is kind of warm, measured @ 26*C. So if at most the temperature variation is around ~5*C.

= built in active cooling

yeah i cant cool the water cooler than the air temperature though, as you claim it magically can

the fans just assists in "radiating" the heat from the radiator, still cant cool it past the temperature of the air, just do it faster

you wanted to see the active cooling..................you never said anything about wanting to see the refrigeration units. what a refrigeration unit is, is basically a large high watt peltier on the radiator usually under the fans.

rofl....ok....free lessons..............in water cooling, the water IS indeed cooled itself...if you've never read a "review"of a water cooling rig like you said, you'd know that water coolers run water through a set of tubes that run back to a radiator. most radiators have refrigeration units..unless you build your own and leave it out intentionally...

where is the one with the refrigeration, you said most have them?

lol..............................i think all you guys with those unbelievable temps are lying :p:p.............my tbird 1.4 runs ~48+ on a huge alpha 8045 that's fine with since before that i had an sk6 with a delta screamer that made me deaf

I swear to god that i'm not lying about my temps. they do fluctuate under usage. the Asus software (and the BIOS) both tell me the same info.

You have your sensors backwards, it is impossible to have your CPU cooler than the air temperature

It's just simple thermodynamics. If all you are using is a simple radiator (a thermodynamically passive device) with water cooling, the CPU (or anything else) cannot be cooler than the air (this is physical law). If you are using a thermodyamically active device (that is, it runs the Carnot cycle or other variant in reverse), you may calculate how much power your cooling system takes and divide that number by 2 (even the Carnot cycle has only about 50% efficiency). Call that number X. Now you can place that computer over a container filled with water (just make sure that the exhaust coming from the power supply is hitting the water's surface and that the surface area of the water is large compared to the exhaust port of your power supply) and measure how quickly the water heats up. This number can be converted into a measure of power. If that number is larger than X, you have an impossible machine. Congratulations.

The point: if it is air-cooled (and yes, water counts too), the CPU cannot be cooler than the air. I don't care what your sensors say because they're wrong in that case. If you employ active cooling (like peltiers or some other device that provides actual refrigeration), then yes, it is quite possible to have a cooler CPU (refrigerators work using active cooling). Just wanna make sure that you don't trust those sensors too much, even if the motherboard manufacturer made them (just think back to two missions to explore Mars that NASA headed recently which went sour).

well said, some people here cant grasp that law of thermodynamics

by their theroy, I could drive my car on a hot day down the interstate at 85mph and hold a cup of water out the window and it would freeze lol, thanks man

ahahaha thats a classic

no sensor is 100% accurate on mobo's

i seen somewhere that asus sensors are quite bit of the scale

this thread is almost as bad as the amd v pentium war except with ppls temps

think ill stick some ice cubes behind my fans in future :p j/k

theres always some prat has to be different and come out with liquid cooled pc's tho your totaly screwed if pipes leak, pour in some anti-freeze while their at it.

and as yeh were sayin username yeh of course yer right only as good as the air temps like some ppl been braggin on this site with 17 - 21 case fans wtf good is it if yer room is warm, really need a really good air conditioning system for yer house to keep it all cool as how most ppl here want their systems

soz for way im typin btw rushin and cant be arsed as its 4am

but as for AMD sayin 60 is limit or whatever why would they lie?

this tbird 1466 runnin at 44 - 48c because room is quite warm so.. what, 52c when playin q3 fine does the job 2 case fans case runs usually 26c to 31c at night copper orb 6k heatsink and fan

its like runnin an engine to cold is as bad as to warm

how bad does it need to be for ppl coolin their systems with liquid and nitrogen lol thats just takin the ****

anyway im out 4.05 :o

yeah, same for my Athlon XP 1800+ but isn't that loud? My system is quiet and i'm using a ThermalTake Volcano 7 (not the plus version) and it's about 3000RPM now and my temp is 41C :). @3000RPM it's about 29DBA ... (i think)

Yeah the temp sensor on my ASUS reads high. Theres no way this chip is that hot with a HSF/fan that powerful :p
