How are the temps? Is the pump as noisy as they say?

I wasn't terribly impressed with my first adventure into the AIO world of water cooling either. I went from a Cooler Master V8 tower to a Corsair H80i and only gained a few degrees. I went from 70-72C under load using Intel's Extreme Tuning Utility to 68-70C. I think part of my problem was the ASRock Z77 Extreme4 motherboard I was using at the time. It was really thin, flimsy construction and I don't think the pump was making good contact. After I replaced the Extreme4 with this MSI motherboard my temps dropped another 2°C. The finish on the pump base of my first H80i was all swirled and grooved too. Moving to the H220 gave me a tremendous drop in temps. Instead of reaching 60-62C in BF3, I now hover around 50-52° and that's with warmer ambient temps. I probably gained 8-10 degrees better cooling by upgrading from the Corsair H80i to the Swiftech H220 with Noctua fans. NewEgg dropped the price on the NF-F12 fans to $24.99 again. That's what the price was when I bought mine plus I had a $10 discount I applied toward their purchase.
It looks like an additional 20% off for a while too: http://www.newegg.com/Product/Product.aspx?Item=N82E16835608026
 

60C is a very respectable temp. I am impressed with that Eisberg. Mine is idling around 30°C right now with ambient around 71F.

I wish you the best of luck. I never ran IBT with my other coolers. I used Intel's XTU but since I removed it to make space on my old SSD, I can't get it to re-install. I keep getting 'Device not supported' errors and can't continue with the install. Anyway, I ran IBT on Maximum for about 15 minutes and temps capped around 65-67C. I did a full run on 'High' with the same results. Temps were mostly around 64-65 and only peaked at 67 for a split second. This still recorded 67C as the peak temp though.

I went ahead and brought it down to 182 BCLK for 3.8ghz. That set the QPI at 3267.7 which seems close enough to that 3200 they state as max.

Looks like no matter what I do the Northbridge runs super hot. I'm not so sure it's because of me OCing the CPU as much as it's just X58+NF200. Tried a few different clock multiplers and 30x, 27x, 24x. Been up to 4.2ghz and down to 3.2ghz and no real effect on northbridge. It's consistently idling at 85C no matter what. Doesn't look like anything is effecting the northbridge temps too much other than it's just hot to begin with. Makes me think I need to reapply tim on it. Later I'm going to google around and see if I can find pics of other's E762's and see if any have pulled the chipset coolers. I'm hoping it's all to do about crappy dried up paste that I can just fix with some MX-4.

Yep. I could probably put a larger one on it though.

Much better. Some TIM might be necessary too. Any performance results yet?

Messed around with OC a bit before sleep. Walked it up to 4ghz. 4ghz was being pretty temperamental, so I backed it down to 3.9ghz. Temps seem decent enough at 3.9.
 
Chipset kept at around 65C while CPU maxed around 75C.
 

Messed a little more with OC this morning. Looks like some of the problem was stability with the 24x multiplier. Backed it down to 23x and upped the BCLK to compensate. Have a stable 4037mhz now. I'm going to see how this is for a day to see if I experience any stability problems with real world use. I might also try a 22x multiplier to see if I can get it higher. The CPU temps are about 5-10C more than I'd prefer but nothing really bad imho. The 360 Monsta rad should help handle that next month.
