Ok Zap you are right, i mean real enthusiast watercooling
I picked up my HTPC parts today including the H70
Ill say this about the H70, dont try and put it in a Nmedia HTPC-6000 case. Just dont do it, its not a good idea, it will cost you blood, sweat and tears.
Bad things happen when you let your girlfriend pick the case, and she told me i could not drill any holes in it or modify the exterior. She thinks it looks great!
When i look at it i have nightmares of the last 3 hours i spent trying to get the god damn rad mounted, and then everything else installed. And figuring out where to put the HDD since i had to remove the HDD cage. Also lost the ability to mount an internal optical drive as it was attached to the HDD cage. But this doesn't bother me as all my DVD's have been ripped onto my server anyways, and i have an external optical drive for OS installation or if i want to watch a DVD i dont have ripped already, i intend to get an external blu ray drive in the near future.
So the H70 is in there now and im waiting for the glue to dry(dont ask). And as soon as it does ill fire it up and see how the H70 works out. I decided a 7750BE was a complete waste of time and not worthy of the H70 so i bought a new C3 stepping Athlon II X4 635 for $100. Maybe ill get it to 4Ghz, overkill for a HTPC but figured it would be fun to play with. Was going to buy a Phenom II 550/555/560 for $100-$120 and hope for core unlocking but they were not in stock when i picked up the other parts and i had to settle for the athlon II.
Quality wise the H70 is great, looks well constructed and the fans look like good quality units and are not super loud at full speed and move a good amount of air. But i will say the water tubes are short and it will limit where you can mount the rad, and they are not very flexible. Also the 3 pin connectors on the included fans are very short and unlikely to reach your mobo headers depending on where you mount the rad, i used 3 to 4 pin adapters(which were not included) so this was not a big deal as i got some extra length from them.
Will post temps in the morning when i fire it up for the first time, and install ubuntu, hopefully i can get the sensors applet working ok with that mobo, and hopefully it boots with that CPU.
