Summary: Just wanna say this thing is awesome, but you always take the risk getting something with defects.
Pros: Worked great for about 3 weeks. Kept my fx email@example.com Ghz around 40 celcius most of the time, 50 at max load.
Cons: After working properly for 3 weeks, my computer wouldnt turn on. After trouble shooting and realising my cpu was nearly melting at 110 celcius, I found that this item had a leak! Luckily nothing else was damaged. But until I get a new one I'm stuck with the stock cooler.
Pros: I had wrote a review before, and was pretty satisfied with cooler even though I had to add fan to get the temps where I wanted them, no big deal, I think they even mention to do that on high perf. setups.What I'm writing about is the fan started to make noise- I brought it to the attention of Zalman and was promptly sent another fan. KUDOS TO ZALMAN.
Summary: I bought an Intel Watercooler and they use a plastic backplate that will not mount the Intel cooler solid to the motherboard. This Zalman fits SOLID. Also most cases have a hard time fitting watercoolers because the radiator is over sized.. But not this Zalman.. No wonder it got a 2013 CES Award. Its a good quality product and I am very happy I made this purchase.
Pros: Runs cool and quiet on an Asus Maximus Motherboard. Installs solid to a metal back plate. Fits where ever you have a exhaust 120mm fan. Looks cool.. Temps dropped 10c compared to Intel watercooler.
Cons: Maybe a slight ball bearing fan noise when my case is open.
Summary: when i overclocked my cpu this didnt do as well as i had hoped it would temps under load were in the 50's and got as high as 60 but my cpu is an fx9370
Pros: I use this to cool my fx 9370 and it does a great job keeps it around 18 at idle and around 33 most of the time under load with spikes up to 40. I used antec formula 7 thermal paste with it and put a corsair sp 120 mm performance edition fan behind it. also in regards to noise its at a comfortable level as long as you dont have it turned up all the way and it doesnt really need to be.
Cons: the wire on the fan could be longer but this is easily fixed with a extention. Instructions are alittle be hard to decipher.
Pros: I got this to cool an fx-9590 in the nzxt phantom 410 case. At idle the temps are around 50C, and under load (8 mpi threads running hpl linpack tests) it gets up to 80-82C. It was easy enough to install and setting up the pump and fan was much easier since I last had a water cooled rig around 8 years ago.
Cons: I have a second fan pulling on the back side of the radiator, and the processor is still not stable (this could be the fault of the motherboard or the processor itself) and the temps are definitely higher than I would like. Even though this case is large, the radiator does not fit many places. In fact, the only place I could get it to fit was in front of the rear exhaust. I would have mounted it externally, but the hoses were not long enough to do so.
Summary: When doing the install for this I would recommend having a friend to help, four hands made this an easy install. Doing this by yourself could be difficult when mounting the pump. I would recommend that you install the fan first hopefully this is common sense to most people.
Pros: This is an amazing cooler. I have an older board and CPU AMD 955 BE x4. Stock cooler for a few years now and can see an instant change in temps. The blue light is not over powering in the case which I consider a Pro. Fan is also quiet. VERY noticeable difference in VRM temps with this cooler.
Cons: Shroud - Zalman really needs to improve the shroud I do not want a bigger shroud as this would defeat the awesome VRM temps I now have. They need a heavy duty version of the shroud that is on it now. This is where I dropped 1 egg from the rating. It is flimsy as is.
Summary: After enabling 'Silent' mode for the fan in my UEFI, it's extremely quite. Around 1800+ RPM is where it starts to become noticeable, but on 'Silent' mode it's hovering around 1500-1700 RPM. It's just barely louder than my Cougar CF-V14HPs.
