Following on from our stock thermal and acoustic testing, here we re-test the operating temperature of the GPU, but with noise levels normalised to 40dBa. This allows us to measure the efficiency of the overall cooling solution as varying noise levels as a result of more aggressive fan curves are no longer a factor.
There's very little to split between the iChill X3 and Gaming OC in terms of noise-normalised GPU temperatures. The iChill X3 does run fractionally hotter, but only by a couple degrees when looking at the Hot Spot temperature. Both are clearly excellent cooler designs.
Likewise for the memory thermals, the iChill X3 actually comes in 2C cooler, but the results are so low anyway it's not hugely consequential.
