The only regret is that the fan holes on the 'other' side of the radiator from the fans it comes with didn't line up with all 8 holes on the radiator. So I just lined up 4 of them, and it is in there good! This is only something an Antec 1200 case owner would notice-IF they wanted to do something crazy like I did.
I'll upload some pics here to illustrate!
EDIT: Ends up I can;t upload any pics! Luckily, I have them all here:
I wish I could upload a screenshot of IntelBurn running on all 8 cores, 100% CPU, full RAM... The FX-8350 (8 core) runs all day at 43degF, and completely SLAMMED (100% CPU for 10 minutes, 95% RAM, Visual Studio, MSSQL 2012 SSMS, etc. all running, too), I cannot get it to go hotter than 83degF (and that is Fahrenheit, not Centigrade/Celsius!) I am using 4 fans (2 in front, 2 in back), and the FB Photos will show you the complete installation from unboxing (if Amazon lets me post the URL).
Installation was as simple as installing any other aftermarket CPU cooling. The heatsink got in the way while I was trying to install the radiator but that's to be expected with any water cooling solution. I was able to use brackets from my old CPU cooling system so that was standardized as well. Against my better judgement I used the thermal paste from the packaging and it surprised me by working very well.
I instantly noticed huge drops in temperature that I could not have gotten without water cooling. I was previously sitting around 40C idle to 60C under load. This brought me down to 40C under load. I expected results but nothing so drastic! I overclocked my CPU as much as I could while keeping the load temperature around 60C.
There was one major drawback. I use a HAF 932 case in order to keep my rig quiet but cool. This thing is by the far loudest piece of hardware that I've ever installed. There's no real solution since it's obviously the fans that are on the radiator. I knocked a star off because of this. The only solution would be to get a fan that is larger than the entire radiator which would look strange and would cost aftermarket dollars.
If you're having temperature issues on your CPU and you don't mind it being a little loud then this was made for you. If you're a stickler for noise then carefully consider alternatives before buying.
READ THE INTRUCTIONS! Yes, that goes for all of us guys out there. Do this BEFORE you even mount the MB, as some sockets will require a piece on the back of the board. Others only require it on the front. The mounting brackets only mount one way, and even though it looks right it will not attach unless you have it correct. Simply put, it will save you from damaging your MB, CPU, or the cooler itself by taking 5 minutes to ensure you know EXACTLY how it mounts, not just assemble logically.
this works great, my cpu has never crossed 37C even while under load. I only wish that there was a way to visually confirm that the fluid was moving, as the fans are powered seperately. I get a little nervous that the pump might go out and there will be no notification to me.
Fitting this in my Corsair 350D above my Z87 Gene VI was a major hassle. 8 pin CPU power hinders the install (Just wrap it around and plug it in AFTER you install the radiator) but that is not the manufacturer's fault.
On to the good stuff...
This thing has my Haswell 4670k running at a rather mild 4.2ghz. At idle it doesn't exceed 40 degrees Celsius and I only have the fans running at ~1040 rpm.
This overclock is stable and reached a max of 79 degrees Celsius under a very high load on Intel Burn Test. May see what I can do with higher fan speeds and a higher overclock. Will update with results.
Very, very good product thus far.
Fans did vibrate obnoxiously against my case upon startup. I just lowered the speed in my bios.
UPDATE: This puppy has my 4670k running at 4.6ghz... HASWELL... 4.6ghz
...and it doesn't break 80 degrees under Intel Burn Test.
