Is this a prank or are you on some kind of fault finding mission with statements like this running from thread to thread ?..... I am finding it somewhat surreal to see an OCN "regular" post a message indicating that they are somehow unaware that a "running CPU" will have higher temperature than the liquid used to cool it. If that were not true, then the term "coolant" would not be a very descriptive label would it ? My coolant is generally a good 40C below my CPU cores when it hits 75C under torture tests..... generally around 1-2C cooler when idling when fans spin down to 400rpm.
1. The statement you are finding fault with says "I hope thatz not a DW loop with water temps
are below freezing
2. Your counter says that I'm wrong because no CPU temps
are above freezing
Well water temps and CPU temps are two different things and it's generally accepted here on OCN that, laws of thermodynamics not being broken, the latter will always be higher than the former. But before getting to that, lets look at the his image carefully.
3. When I look at the image of his CPU temps I see this label entitled "Minimum" and when I look at it, it says that one CPU core temperature was at some point in time .... a time SINCE the program was loaded ..... 0C..... So when he took the screen shot, it was 1C, at some time previous while the program was running, it was a lil colder at 0C and at when it was shut off and not producing any heat, or even sleeping wouldn't it be colder still.
4. Can we agree then, that an actively running processor is going to be "warmer" than one in a turned off / or "sleeping" machine ? So if the warmed up CPU core is 0C" then before it warmed up, it must have been at a lower temperature.... if it was at a lower temperature than 0C the core must, by definition, have been "below freezing".
5. If ya can't agree to that, let's talk about what the subject of my post being "water temperature" not CPU temperature. If we can agree that the stuff in the loop is called a coolant..... we must also agree that the coolant .... must be "cooler" than the CPU if it's going to serve its function. If the CPU was at 0C and it was producing heat, then isn't the only reason it's not climbing higher because the coolant is of a lower temperature ? Is that not the whole idea of water cooling ? .... the coolant, being of a lower temperature than the CPU, functions to cool the CPU down ? So if the coolant must be cooler than the little heat factory we call the CPU cores, and the core was at 0C at some point, then must it not follow that the coolant must have been lower than 0C ?
6. Right now I am looking at an ambient of 20.1 ..... a "CPU In" coolant temp of 21.3 and a "CPU Out" temp of 21.7..... So I think it's a safe bet that my cores are no cooler than that 21.7 .....so if my box was in that same basement with a core temp of 0C, then I'd have to expect my coolant in to be -0.4 (21.7 - 21.4) while running and drop to ambient when shut down of at best -1.6. (21.7 - 20.1) . Those two numbers are below freezing.
