Question: installing the antec Kuhler H2O 920. before I tighten it down on the cpu do I need to smear the grease on the cpu???
Document: Hi, I currently have rog crosshair v formula-z and a FX 8350 Black Edition Processor with Antec Kuhler H2O 620 for about a year now..at 1st the cooler is very good but after a year, the standard temperature is around 59 celcius and i havent overclock it yet..need help on this! !
Antec Kuhler H2O 920 . It's not as loud as some people have mentioned only when it's at full load , it is quiet on the silent mode. fan unit as it comes with software and the fan speed can be set to how you like it . ChillControl Version 1.2 released and fixed problem with USB driver.I'm running an FX-8120 CPU,3.8ghz,1.286v 35c idle . 52c running prime95 1 hour 35 minutes.Cons:The fans are very loud on full speed
You probably don't even need the Antec program, but it does allow you to monitor coolant temperature (always 2-3C cooler than the CPU temperature) and set fan speed thresholds to customize operation for your system.When I installed the Kuhler 920 I plugged its USB cable into one of the 14 USB 2.0 ports on the motherboard. The software automatically found it and ran with no need to configure anything.I installed the cooler with the fans blowing air out of the case.
The Antec H2O 920 cooler is advertised as a simple installation system. All you supposedly have to do is install the software, and then follow the steps to install the hardware. Wasn't so simple. I installed the software, but the cooling system couldn't fit in the casing anywhere(I had a mid-tower case). No matter where I placed it, it interfered with something important on the motherboard.
Point is... the Antec Kuhler H2O 620 is true to it's claim: quiet! If there's any noise at all, it will be from your choice of fans. I recommend you ditch the Antec fan that comes with this unit and replace it with a quieter fan. Then your jaw will drop as to how ghostly quiet this thing is!
I was having a problem with my older cooling fan for my new(ish) Intel Dual Core E8500 processor. The heat was getting to the max of 100c way too often. I tried new thermal compound but that did not help.I bought the Antec Kuhler H2O 620.
I needed a better CPU kuhler because I was trying to push my i7 920 to 4.0ghz and my other fan was not keeping the cpu cool enough. Here comes the kuhler 620 which keeps my cpu at around 50 c which is amazing especially since i'm over clocking my cpu by so much.Further the other amazing by product is that its so quiet!!! My last fan made a ton of noise and this one is nice and quiet, you have to listen hard to hear something.
I hesitated before going with a water cooler since I had a bad problem that killed a $520 video card back in 06. Well I went with the Antec 920 since the price was really decent, and after reading all the horrible reviews about the Corsair coolers (Thanks everyone)It was a easy choice.Yes the instructions are just un-useable! Simple enough to watch a You-tube video if you need to, I did just to double check things. Installation is not hard, but is tedius.
the cpu block doesnot put stress on the motherboard as its lightweight and doesnot block anything. There is no need for additional space in terms of a minimum cabinet size as all it needs is a 120mm  fan space and it may also be mounted outside the cabinet if need be via a swiftech or a xspc radbox. The tubing are not that long so one might have problems mounting it on the top or the bottom of a large cabinet.Performance:Kuhler keeps its about 10-20*C cooler than the v8.
The 120mm fan included with this &#34;Kuhler&#34; is MUCH more quiet and moves alot of air! Not only does it lower my CPU temps, but it lowers my internal case tempurature also. I would recommend installing this Antec 620 if youre looking to install a cheaper 'liquid cooling' device.BAD NOTE: The install process is not well documented. I watched a video on youtube.com to help with the install.
Answer: The cooling pump already has the Termal compound on it.  Use that.  If you apply any extra it may cause create a *bubble* increasing heat temperature and cause overheating.  Make sure to clean the cpu from the old termal compound.  Hope this helps.
