Pros: Works very good. Keeps temps 31c at idle and never over 52c with a load.
Cons: Minus one star for rebate. Don't hold your breath waiting for it. I sent mine in over 3 mo's ago, recieved an email saying it was recieved and to expect a rebate. Said rebate is way over due. Bought 2 of them and will buy more if said rebate ever gets here. If not , will never buy from Zalman again.
Pros: worked as advertised, extremely good looking and very quiet.used this product with a i7 3770k- asus p8z77-v lk - 16 gb g skill 2400 ram- 750 watt corsair psu - mounted in a fanqua mid tower, bottom mounted psu case
Cons: instructions really should have a pic , or a diagram of 1155 back plate position on mobo, it has to be crooked , at a angle to get all 4 screw holes to line up to mobo holes. almost sent it back, but kept moving it around , and around till i got all 4 holes aligned to mobo, but it looks like a hack job from rear of mobo. no taking away a egg here,but i bet some buyers send cooler back thinking zalman cant measure holes correctly.
Summary: Getting the pump retainer snapped into the bracket was a bit tricky.
Pros: A quiet pump, no leaks, radiator fit my old cooler master case just fine, lines are thick and soft for easy setup, the fan is a nice unit that moves some air, not a single bent fin in the radiator, and decent hardware. It keeps this 3.1 ghz Athlon Dual core nice and cool. Beats out my good old Xigmatek Heat pipe tombstone by 6 degrees C at idle and 11 under full load running Prime95. With 2 less fans in the case, the system temp is about 3 degrees C cooler.
Cons: Nothing serious- some quibbles might be having to remove the motherboard to install the backplate, and on an AM2 you have to remove the OEM HS mount bracket, too.
Pros: This unit delivers, equipped with the 3750k I was able to overclock my i5 with this heat sink to 4.4 from its stock 3.4. My temperatures are about 28-32c idle and 48-55c on extreme load. Also it looks very clean installed in my 650D. Oh yes and if your wondering, not that it matters to me but it is SILENT.
Cons: The directions do not say what what orientation to face the hoses. I see other people online asking this question and I have read it can be done both ways. I installed mine with the hoses up, it looks more natural, and it the only way you can see the Zalman logo.
Pros: First water cooler, and color me impressed. Temps dropped 10C from my big heatsink/fan (a Zalman cnps9500), and noise is nowhere to be found. Installs easily. Love the PWN fan control, a big plus. A "push" design rather than the "pull" of a few other single-fan units. Zalman brand is one I trust.
Cons: Instructions could be better. See review below for very helpful tips. But not enough of a problem to cause and egg reductions.
Pros: Very Very quiet. Cools my i7 3770K was getting around 25c-30c on cold boot and running some video encoding it stayed within the 50-58c range and this is at automatic fan control with minimum setting set to 40%! It never touched 60 at all !
Cons: None ! This was an absolute blast putting together my first water cooled cpu together.
