For the past year or so I have used a kraken g10 with a 240mm rad aio on my gpu.

The temps have been great but the air that exhausts from the rad is uncomfortably hot. So much so I have had to put the fans as exhausts.

I have just upgraded to a alphacool eiswolf which is a full cover block with pump and attached to a rad.
Unlike the AIO this cools the whole card and not just the core.

My temps are cooler and the air coming out of the rad is barely warm so I have set the fans as intakes.

I would have thought that a full cover block rather than a small block covering just the GPU core would put out more heat.


Can someone explain the physics of this If my post makes sense
 
If your card us using the same amount of power, then yes, the same amount of heat should be generated at one point or another. Looking at any voltage / power use before and after would have been an ideal way to measure.

However after that hard to say as without numbers and only feeling by hand the heat coming out hard to say. However, unless I am mistaken, the block while full coverage, only actively cool's the GPU core with Eiswolf block's. The VRM's and power delivery etc are all cooled via being connected to a large fin heatsink which in turn is connected to the GPU core block (so heat transfer's from fin's into actively cooled GPU core block). Could very well be that as its a large block of metal fin's, any case fan's or airflow is working to also remove some of the heat from the fin's aswell.
