I just completed my second WC system, this time using an Eheim 1250 inline with a res / airtrap. I've got the pump mounted on rubber grommets and the mounting screws also have grommets on them so that the pump mounting rails should be pretty well isolated. However, this pump still has an annoying vibration and low pitched hum.

I built an add-on wooden case to house the watercooling componets, and it screws on to the right side of the computer case. I've used rubber feet on the bottom of the case, and even with the whole thing sitting on a folded towel, I can still slightly feel the pump vibration on the floor.

Is it normal for this pump to vibrate so much?

I'm quite happy with the performance of the system. It uses a DD MazeII on the CPU and another DD block on my Gainward GF3. The radiator is a 4 pass 5 1/2 X 11 heater core recycled from the junkyard for $7.50! Two 120mm aluminum Sanyo Denki fans cool the rad in a surplus shroud that fits beautifully and has rubber isolation mounts for the fans. I can switch select one or both fans and drive them at 7 or 12V. Very quiet even at full speed.

My XP1600+ is at 1610mhz in a Soyo Dragon+, and I haven't seen the temp go over 40c yet (stock on-board thermister).

If only that damn pump didn't vibrate so much! Any ideas?
