More radiator better cooling? - Page 5

post #41 of 47
this is what I have gathered so far from the information provided.

shadowman007 has a CPU hitting 86C, on a water loop that has a delta T of 15C while the system is at load.

The thermometer has different settings for different thermocouples it has types like K/J/T/E/N/R I had it set on the WRONG type rolleyes.gif my thermocouple is type K. Anyways after running Aida64 for about 15 minutes water temperature was at 40c I hope this is ok? But the fact remains like mentioned before fittings, water block are hot even the radiator is blowing hot air.

so to me this means that a second 360mm radiator should bring the delta T of the system down to a 5C or better. this will in turn bring his load temps down at least 10C as well.

so with the addition of the second 360mm radiator his CPU should not go above 76C at load.

my earlier example was simply to explain that it is possible to over clock a CPU beyond any water blocks ability to cool it, no matter how many radiators are on the system.

it is possible to have a 3C delta T, of the water loop, and a CPU temperature of 85C, with three 360mm radiators cooling the CPU only, on a highly clocked CPU.
at that point, it's not about the systems ability to remove heat from the water, but the blocks ability to transfer that heat to the water. wink.gif
thus the reason for my extreme build. rolleyes.gif
http://www.overclock.net/t/1584867/tec-chill-box-chamber-build-log

delta T of the system is the temperature difference between ambient temperature of the room, and the water temperature of the loop at load.

40C is 104F that would make for really warm air coming through the radiator.
86C is 186F that is enough heat to make all the fittings connected to the CPU hot.

Just out of curiosity, do you have any tools available to get a reading of how much power you're drawing from the wall? 125 degree VRMs on the motherboard coupled with a fiery CPU sounds like a lot of power consumption.

You could be at the limit of what your CPU block can dissipate into the water in the loop if the water isn't getting that hot. Either a bad mount on the block or a bad repaste after the de lidding could cause this, or clogged fins in the CPU block.

125C on the VRM,s maybe try to get a little more air to them.



I put a fan in my PC case to blow down on that area, and help with the cooling of the motherboard around the CPU. thumb.gif

I cleared this in post #18 of 43 my thermometer was on the wrong settings the VRM temps at full load were actually 51c

Aida64 with the following checked:

Stress CPU
Stress FPU
Stress cache

full load from the wall was pulling 430 watts however did hit max 480 watts but stayed between 426 - 430

My fittings the water block itself is very very hot. I mean this is a delidded cpu with a 1.22v getting cooled by a EK XE 360 radiator with 3 EK Vardar fans running at 2200rpm surely water temperature can't get this hot? Seems like everything is heating am in my case even the VRM is over 125c eek.gif even though this is the Asus rampage VI Apex motherboard with a better heat sink.

I agree that water near the boiling point in your res would definitely be cause for alarm. I'd imagine something was seriously wrong with your loop if that were the case. biggrin.gifbiggrin.gif

The EK XE360 is a thick rad at 60mm, maybe an idea to look at a push pull config? A rad of that size should be ample to cool just a cpu
