Pros: fan is slient

Cons: When the computer is at a low-temp state where the fans and PSU are very quiet I can hear a noise coming from the pump area.

Pros: Was easy to install it in my Chaser MK-1, great performer overall with the included fan. With my 3770k @ 4.4Ghz torture testing Prime 95, temps only got to 50-51c at peak times, idle lows around 30c (California is hot! Your experience may vary from dif room temps).

Cons: Pump makes small noises, but is impossible to hear without putting my ear close to my case. The stock fan gets really noisy if it goes over 50% of max RPMs, but it doesn't really need to go above that for good temps .

Ordered a pair of SP 120mm high performance fans to see if there's a dramatic drop in temperature with the extra air flow.

Other Thoughts: This is my first liquid CPU cooler all-in-one, glad I went with Zalman. Highly recommend it.

Pros: Nothing.

Cons: I should had listen to the review that said this thing was conductive. It completely kill my processor.

Here is the difference in sound output.

Cons: None that I am aware of yet.

Pros: Currently mounted on a fx6300 clocked at 4.5ghz. Previously cooled by a push/pull hyper 212 evo. Currently core temp is 12C lower and socket temp is 6C lower vs 212 on OCCT linpack (20gb memory usage).

Significantly quieter vs air cooling.

Provided I get rebate, it is only about $10 more than a post-rebate 212 evo, same price is you account in a second CM blademaster fan.

Cons: The AMD mounting instructions are nonexistent. Unless you have mounted a couple of these things before, you will have to rely on some guesswork. The intel directions however, for lga 115x are quite thorough, so intel users are perfectly safe.

Other Thoughts: Missed this the last time it showed up on r/buildapcsales, was pretty fortunate to catch it this time. If you are going for bang for buck performance in the <$40 bracket, your options are limited but this performs admirably.

Pros: 1, cheap but offering good performance
2, the cooler has blue LED when it is working
3, fan is slient

Cons: 1, two double side foam tapes are missing. They are tiny items which decrease shakes and noise when it is working. I compared everything between items in the pack and descriptions online very carefully and found that.
2, Newegg service agent could help nothing because s/he couldnt see it.

Other Thoughts: I recommend it to potential customers if your devices aren't beasts. But you need to check everything carefully when you get the pack. Some accessories are really small and easily being overlooked.

Pros: Shipped Fast

Cons: Res was half full....that is completely unacceptable on a AIO unit. After working out all the air bubbles the pump was still very loud....sent it back.

Pros: Cools very well.
Looks pretty nice.
Small form factor.

Cons: None

Other Thoughts: As a first time AIO cooler user I didn't install the radiator correctly at first. With the rad lines coming out of the top this thing was VERY noisy. Once I flipped the rad over so the lines are on the bottom and gave it a few days to work the air to the top it is silent.

Using this in a NZXT 340S case my 5820k runs at idle around 29°C and under full load around 50°C! Can't beat that at the price I got this at!

Pros: Shipped Fast

Cons: Pump was completely non functional, Sent an email to Zalman, zero response, just returned it, onto another brand.

Pros: keeps my cpu at extremely cool temperatures, and it does it while staying rather quiet. much cooler temperatures than the air cooler i had before and much less audible. worth the price.

Cons: -while extremely quiet you can sometimes hear the pump, but only if you're in a very quiet room.

Other Thoughts: -radiator is rather large, didn't fit in the 120 mm spot with out me setting it up with two fans. Radiator would hit the io ports on my mb so the second fan elevated past that point and allowed me to mount it.
