Actual influence of flow rate on system temps

[gabe]

I would have to test with just waterblock and no active gpu to confirm that changes in flow dont alter water temps in that circumstance, though you may have already done/know that.

Yes it's another way to do it, but unnecessarily time consumming. The rise in coolant temp due to GPU heat is unequivocally showed by [(ΔT Water to Air test 2) - (ΔT Water to Air test 1)]; when substract this result from [(ΔT CPU air Test 2) - (ΔT CPU air test 1)], you isolate the rise in temp due to pressure drop, since its the only factor left.

btw...planning on any testing with 2 360 rads...one of the most common scenarios is 1 loop or 2 with 2 rads.

This describes our Xtreme bench (also mentionned in the body of the article). Ppl have complained that it is too extreme. What we have done (not yet published though), is testing dual loops with a 320 and a 220. I am trying to test configurations that can be easily (without major mods) integrated inside of a case, which I believe represents what the majority of ppl would like to be able to accomplish. The very popular Cosmos S for example is capable of integrating a triple and a dual without any major mods.

Gabe, with BOINC just connect to milkyway @ home. This can be set to use 100% GPU and then you can fold with your CPU as normal on WCG or whatever you like. I'm using two loops so I can fold GPU and CPU 24/7... This kind of test data would be very interesting to me since I have three 120.2 rads across two loops.

Finally, great work on the data above and many thanks for sharing your findings. I found the data very concise and very informational.

I did already, and it is set to use the GPU, but all I get is 57% load on GPU #2. I need to reach 100% on both GPU's in order to have comparable results.
