dreamworkz Posted February 27, 2013 Share Posted February 27, 2013 howcome when dropping from 100% cpu load to 10%, the temperature of the cpu drops 30*C within 3 seconds? is this possible? it makes no sence to me also, howcome running max rpm pwm fans (the new ones sent via corsair rma) at 100% cpu load does not drop below 60*C? (overclocked ivybridge 3770k to 4ghz) is the corsair temperature gauge 100% accurate? as speedfan (what i used previously gives an entirely different result :S) also, when changing the speed of the two new fans on the radiator, the temperature doesnt seem to differ at all within corsair link, but does within speedfan hmm? will 1.0.5 firmware fix this problem?

Synthohol Posted February 27, 2013 Share Posted February 27, 2013 i hope you are not running both monitoring apps at the same time, it will make both inaccurate. take a look at hardware monitoring in the bios for like 10 minutes, that will show your temps under load as accurate as it can be. also yes its possible for the temps to drop that fast.

(overclocked ivybridge 3770k to 4ghz) The heat is transfered from CPU to the block and then to the water and then to the air. As you can see there are many obstacles to the heat transfer. is the corsair temperature gauge 100% accurate? as speedfan (what i used previously gives an entirely different result :S) There are some post saying that is not as accurate as speedfan. also, when changing the speed of the two new fans on the radiator, the temperature doesnt seem to differ at all within corsair link, but does within speedfan hmm? will 1.0.5 firmware fix this problem? Link has a higher lag then speedfan, and I don't think the new firmware will fix the problem Link to comment Share on other sites More sharing options...
Ragingsoul Posted February 28, 2013 Share Posted February 28, 2013 If the liquid is very cold then it is possible. nothing to do with how cold the liquid is. It's all about where the sensor is located. The temperature for the processor itself is within the chip, thus, the 100% load will instantly generate more heat, and will also instantly decrease it when load is dropping. The temperatures near the CPU and of the liquid will behave a lot less rapidly. Obviously, a cooler liquid will have greater impact on the internal temperature, but then we are talking about liquid nitrogen. With water at room temperature, the impact is really minimum. also, howcome running max rpm pwm fans (the new ones sent via corsair rma) at 100% cpu load does not drop below 60*C? (overclocked ivybridge 3770k to 4ghz) The heat factor isn't the frequency, it's the voltage you apply on your chip. 60 degrees isn't much anyway and is totally normal if you're looking at the CPU temp. they can go up to 105 degrees. You should be around 75 degrees at around 4.5Ghz and 1.18V VCore. The heat is transfered from CPU to the block and then to the water and then to the air. As you can see there are many obstacles to the heat transfer. Actually, the heat goes from chip to the heatspreader (IHS) through a thermal interface material (TIM). Then it's transfered to the waterblock, through another thermal interface material and then to the water. Link to comment Share on other sites More sharing options...

Ragingsoul Posted February 28, 2013 Share Posted February 28, 2013 Ahhh. You do agree with me. Thats why I've sad Liquid and not water. he is talking about watercooling. You'll have the same 30 degrees difference more or less with liquid nitrogen. But instead of going from 30 to 60 you'll go from like -170 to -140. So you're phrasing is misleading. for someone starting, he is gonna get crazy ideas like putting the radiator in the fridge :eek: Link to comment Share on other sites More sharing options...
