Tweaknews: Top Rank Award : November 2009

"To sum it all up, Cooler Master's new Hyper N620 CPU coolers is BIG, both in physical size and performance, yet leaves a relatively small acoustic footprint. The included blue LED fans are a nice addition and the mounting solution is very robust, if a bit fussy to install. If maximum cooling and impressive looks are at the top of your list when shopping for a CPU cooler, don't overlook the Hyper N620."

» Details : September 2009

"This is a cooler I would be happy to have on just about any system.  I was more than a little pleased with the CPU temps and happy that my other temps didn’t change much. Installation was a breeze with my case mod.  I was also happy to have the PWM fans.  Most modern motherboards accommodate this feature to control fan speed"

Thinkcomputers: 10/10 : September 2009

"The twin offset fans both allow for airflow over the cooler's oversized radiator, and extra airflow to provide silent running even when an overclocked CPU is under load. The performance is excellent, amply cooling that hot 130w i7. It gave nearly the exact performance as the most expensive air CPU cooler on the market."

» Details Recommended : September 2009

"Overall, Coolermaster's Hyper N620 is a heatsink I totally recommend. Not only does it look pretty good, it's also well built and, best of all, it performs right up there along with the market leaders."

OCC: Silver : September 2009

Futurelooks: Recommended : August 2009

"The Hyper N620 definitely has the bases covered with a polished base, many heat pipes, and lot’s of cooling surfaces. Plus, there is as much as 83.6 CFM flowing through the cooler at max. Most importantly, it is a nicely constructed CPU cooler offering great performance at very acceptable noise levels."

» Details Gold Emblem : August 2009

"If you are looking for quality CPU cooling that delivers outstanding performance and your wallet is just about to start producing moths, the Cooler Master Hyper N620 is an affordable solution that delivers above average cooling at a price others cannot compete with."

Modders-inc - Must Have : August 2009

"Did the Cooler Master Hyper N620 hold up to the testing? Absolutely, it clearly showed that it was up to the task of cooling our 3.87 GHz Core i7 processor. At the 3.87 GHz overclock we had load temperatures in the mid to upper 70's which is pretty damn good for an air cooler."

Hightechhardeware editors choice. : August 2009

"CoolerMaster has hit the nail on the head, as it were, with the Hyper N620. They have created an outstanding cooler that will help eek out every MHz out of your processor. Both fans on the Hyper N620 are controlled via the PWM headers on the motherboard."

» Details : August 2009

"Most cooling products that come from the Cooler Master labs are both functional and fashionable, and the new Hyper N620 CPU cooler attaches itself to both qualities from the beginning.
