Absolutely excellent. Even cooler than my corsair liquid cooler. Using core temp, the temps show approx 22-29 with moderate work, such as word processing, surfing the weeb and generally just plain easy using,

-Cools Well: my i7-4770 never gets above 55C while playing Crysis 3 -Very Quiet: won't wake people up like other cheaper coolers

Works great and keeps my CPU cool

I purchased this for an older PC I use as an OTA television recorder and for various internet streaming on a television. The stock fan (new with an upgrade CPU) was noisy and temps ran higher than I would like. Temps now run slightly above room temperature for most streaming and recording and fan is inaudible. Mounting was solid unlike reviews I have read for other similar products.

Keeps CPU extremely cool Blue fan will fit in nicely with themed builds Overall design just looks really high tech and cool Almost silent

Attractive design, effective cooling, amazing support from Enermax

This cooler is handling my mildly overclocked i7-4790k with ease.

This unit is made well. I was looking for a replacement for my stock cpu fan to bring down the heat on my i7-9700f and this has done the trick so far

Does its job. Idle Temps are sitting at high 20s, max load temp hit 60 with i7 5820k@3.8GHz. Looks phenomenal

- It does not need fan when used for low powered CPU 80W or less. I used it with a Intel Q9400 overclocked at 3.2 GHz and there was no need for the fan keeping the CPU at less than 50 deg C. - It needs one fan for high powered CPU 90W or higher. I used it with a Xeon X5470 overclocked at 4.0 GHz. The Xeon X5470 is a 120W TDP CPU with a Tcase max of 60 deg C. During normal operation and using one fan, the CPU was kept aroung 50 deg C. During constant high CPU activity, the CPU was reaching and passing the 60 deg C for few seconds. I am going to install the second fan expecting to keep the CPU at healthy temperatures. - I am confident it would work with 150W CPUs as well using two fans, not one.

The Freezer 34 eSports Duo isn't too flashy in terms of looks, but the unique fan design with highlight color does give the cooler a sleek, modern look. Compared to the stock coolers available from AMD and similar products from pre-built PCs, this Arctic is worlds away in terms audible noise. The Duo version offers 2 fans, of which allows for lower rpms and less noise, especially, on a Ryzen 5800x running at full load. Thermal performance is above par from a 1 tower cooler that doesn't even cover the entire cpu lid. I was able to sustain about 79C on a typical heavy load while in tandem with a RTX 3070ti. Installation was relatively easy to install, but you may want to reference youtube videos for this. Be aware that the cpu backplate will be loose until the cooler is fastened on with the thumb screws. Comes with Arctic MX-4 performance thermal paste, of which is very handy and not typical from other cooler manufacturers. Note that the block is smaller than most, and they give you a little extra thermal paste, so don't use too much. The packaging is rather limited in order to keep waste low and the extra parts are not excessive.
