Summer arrived. Kuhler 620 couldn’t cut it with fans running low. Running the fan at 3000RPM all the time, or even when gaming, was not an option. So I had to look for a new cooler, an air cooler to be p
recise, because they could cool pretty much same as a AIO water cooler, while screaming much less.

Note: I did say I won’t add anything new to this PC, but mother nature had other plans! I cannot help that, right?
One problem though. The best in the class air coolers could not fit. There was the limitation of clearance inside the case, but more importantly, the dreaded Corsair Vengeance RAM made it impossible for any cooler to clear their height. So I had to look for something that did not protrude into the RAM slots.
There are very little options. I found the Zalman CNPS9900 MAX, not only did exactly THAT and also performed better than the Kuhler 620!!! Victory!

BTW, the cooler is frigging ginormous! You won’t understand it until you install it. The one I bought was the MAX-B, which comes with a Blue illumination. It is not a blinding light either. Pretty nice looking.
What do I think about the performance? It performs exactly the same as the Kuhler 620 (fan at 3000RPM) while running much quieter. It is NOT silent by any means, but it is day and night when you consider the 3000RPM Gentle Typhoon which was mounted on the rad. (and don’t forget, the Gentle Typhoon at 3000RPM is much much quieter than any other fan at 3000RPM).
Here is a side by side comparison between the performance. Room temps were difference in either case. 30.1C for Kuhler 620 and 26.5C for CNPS9900MAX-B.
Note: These are the max temps achieved in a 15 minute period, while running SmallFFT in Prime95.
