I'm comparing temps between a Corsair H105, and a Corsair H100i V2. The H105 has a 38mm thick radiator while the H100i V2 has a 30mm thick. Both are 240mm
The rig consists of these core components in question:
-Asus Sabertooth x79
-Intel Core i7 4930k overclocked to 4.5 GHz on all cores with HT enabled.
To keep everything streamlined, I am testing with RealBench stress test and using the same voltage.
Test 1) 30 minutes of RealBench @ 4.5 GHz on the H105: Temps Range between 50-60C (Maximum). Don't even have to use max radiator fan speeds. I can even do 4.6 GHz with a voltage bump and do low to mid 70's C with no problem.
Test 2) A couple of minutes of Realbench @ 4.5 GHz on the H100i V2: Temps skyrocket to about 85c+. The computer crashes because it isn't able to achieve those clocks at the given voltage for those temps. 100% fan speeds on Radiators.
I re-seated the block 3 times on the H100i V2, once with a different thermal paste. Then I put back on the H105 for good measure. Numbers stayed the same.
I decided to inspect the H100i V2 while at load and check physical thermals. One of the tubes gets really hot. I suppose this means there is a flow from the block to the radiator. At the radiator where the tube connects it gets REALLY hot. That's where it ends. Nowhere else on the radiator does it even get lukewarm.
The H105: The radiator seems to evenly warm up.
Any ideas?
