Test Bench
For our tests, we used our Project MakeMeCooler Doraemon system which is comprised of a Gigabyte GA-Z270X Ultra Gaming motherboard, along with an Intel Core i5-7600K at default clock speed of 3.8GHz, as well as 16GB of GSkill Trident-Z DDR4-3200 ram in dual channel mode.
We used AIDA64 CPU stress test which produces 100% CPU load and recorded the temperatures for both stock and overclocked CPU speeds.

Temperatures – Default clock @ 3.8GHz
Idle Temps
Idle temps was at an amazingly low 28 degree Celsius, which is the lowest I’ve come across to date. Mind you the ambient temperature at the time of testing was pretty low.
Load Temps
We managed to get some nice temps for the Bitspower Summit EF CPU Waterblock – 45 degrees at CPU full load.
Temperatures – Overclocked @ 4.9GHz
Idle Temps
We got idle temps of around 33 degrees Celsius, which is pretty good for an overclocked i5-7600K @ 4.9GHz
Load Temps
Full load temperatures reach a high of 74 degrees Celsius, which was a little alarming, but it coped pretty well. D@mn! these Kaby Lakes run HOT when overclocked!
In Comparison
Here’s a quick comparison between the Bitspower Summit EF CPU Waterblock vs the Cooler Master MasterLiquid Pro 240 (AIO).
