That pump is history. The last time I had to RMA a pump with Swiftech they kept me waiting for almost two weeks after receiving the old one while Amazon showed they had 23 new ones in stock. I had to file a grievance with Amazon and it sill took me a week to get my replacement shipped out. I should have taken the refund offered by Amazon and got the XSPC dual-bay combo unit. Now my video boards are running 10° hotter than normal. I hope that Swiftech pump didn't lose it's cookies and hurl chunks through my loop. If I ever get my replacement I am going to reapply TIM to the GPU die anyway. I am ready to go back to air cooling.
I am running the H100I from Corsair and to be honest, I haven't had any problems with it.
I was thinking about getting a Swiftech system but after reading about your issues with them, I'm glad I didn't.
If the cookie hurl is in your system then I believe you will be going with a new system. You don't need that stuff floating around in the loop(s) to eventually take out another pump.
The air cooling works great but I don't like the weight that comes with them. I have a N620 by Cooler Master in my other rig. It has since been discontinued. But it did it's job and kept things cool without ramping up on the RPM's.
