So just got this, seems pretty awesome so far.
Minus the fact that I am getting higher temps off of this on my i5-2500k @ 4.3GHz than I was with my thermaltake heatsink with one fan attachment.

Any ideas what this could be?
How to fix it?

I know this cant be right and I have tried re-seating and re-applying the thermal compound (arctic mx-2).
The first installation I got up to about 80c overnight on prime95, and now after re-seating, I am seeing 71c after runing for about an hour or so. So there is no telling what a 10 hour test would uncover in the morning.

Even in BF3 im getting about 60c...
Any help would be awesome.

TT Bigwater isn't really a recommended buy when it comes to watercooling. But, that isn't something that we can really help now, so let's see what might be the issue.

Can you tell if you are getting decent flow? Is water moving? Can you link to the exact kit you bought? Where is the radiator mounted?

that is the cooler.

Yeah i figured as much, but im more of a thermaltake fan over corsair and someone recommended this one to me. I also have the Coolermaster Storm Trooper case, so my rad is taking up the two bays below my cd drive on the top bay.
From what I have seen the water seems to be flowing good. I have a short loop though, and was also wondering if I used longer hosing if that would bring my temps down a few degrees.

Why in your opinion do you feel like the bigwater isnt a good buy?

i did read though that there is design flaw with the cooler. the fan that is mounted on the rad is actually pushing air down into the rad instead of up and out. Which leads me to consider modifying the rad to have a push/pull system and flipping the fan upside down.
I mean, this could be an idea. But after seating and such I would think that I have it seated correctly with the right amount of thermal paste as my temps have gone down a few degrees since the first time I mounted the plate.

The pump isn't that great, but it's not the worst, either. The flow rate is comparable to a DDC but I question the actual head on it. Heck, the X20 750 flows more than a DDC, but the DDC has almost 4x the head (1.8m on the X20 750 vs. 7m for a typical DDC).

I had a couple friend use older Bigwater kits; on one, the CPU block had a flaw and leaked causing MB failure. The other suffered pump failure after only a couple months. They were different design, but TT has never been a valid player in the WC industry.

Well luckily thermaltake was extremely awesome to me and are replacing it with the water 2.0 extreme, plus paying for return/shipping. Hopefully I will do better with this one. I put back my old thermaltake heatsink with copper piping and its giving me about a 10c drop in temps from the bigwater. I will never recommend this product to anyone lol.

The 2.0 is probably a better product IMO just because it's a closed loop cooler that's already based on very common design. I wouldn't be at all surprised if it's not using the same pump and rads already in-use by other vendors and just rebranded as TT. The downside is that a closed loop cooler (CLC) really doesn't perform that much better than most good air coolers and really only outperform them when fans are running flat out on HIGH.

Bigwater has pretty much been a failure from everyone I've ever seen or heard of owning them, which is unfortunate since there was a large market for low cost, decent performing water loops about 5-8 years ago that wasn't being filled the way it is now with closed loop coolers.

totally agree. Damn well I may just stick to my air cooling, I figured I might as well give the water 2.0 a go though, just to see what temps i can get out of it. Im @ 4.5GHz now so a little bit colder wouldnt hurt. However with my thermaltake heatsink, im sitting at 62c on my highest core running blend prime95. So who knows, maybe ill just sell the water 2.0 and upgrade to some crazy heatsink.
