"Aqualia Watercooling Kit"
NOTE: Some readers are writing in about premature pump failures with no success in getting Pentalpha to replace it. Take this under advisement before purchasing.
SUMMARY: Very quiet, very easy to set up, moderate cooling performance.
The good guys at Pentalpha.com dropped me a line a couple of weeks ago alerting me to Aqualia Watercooling Kit and were nice enough to send one to test out. When I first saw it, the thing that impressed me was how easy it should be to mount in a case - no cutting etc., just slip it into a drive bay. This morning it showed up.
I opened the kit and found the following parts:
The kit includes an aluminum/copper waterblock, the pump/radiator/reservoir assembly, mounting clips for Socket A and P4, screws and thermal grease - all you need to get going (except fluid). The fans are low profile 70mm units - they are very low noise (I could not get a reading with a Radio Shack sound meter placed 8" from the fan's intake) running at 2183 rpm.
There is also a very good manual, which takes longer to read than to set the Aqualia up. This kit is REALLY simple. And it is small - I placed the pump/radiator/reservoir assembly on a standard CD ROM to show its size:
The waterblock
is on the smallish side - the nipples ID measures 4mm - this is going to restrict waterflow and hurt performance somewhat. Attaching the tubing is simple - remove the bolts, attach the tubing to the nipples and bolt them to the waterblock. The top is aluminum and the base is copper:
No polishing marks visible or apparent to the touch. A closer look at the reservoir assembly
shows it with the 12 volt pump, with the bottom of the "radiator" at top. At first, the waterpump made some gurgling noises, but these disappeared after running for a while. The radiator should be called a "watersink" (visible from the back):
It's more properly a watercooled heatsink than radiator (at least, compared to those that we typically see). This design is akin to that used by Koolance - which they don't use anymore - and a design that I think is very effective, especially in space constrained applications such as this one. The view from the front
shows the fill port on the reservoir. Remove the fill cap, use the bottle which comes with the kit to charge it, run it and refill as needed. Simple.
Overall, I felt that the watersink was an excellent idea, but compromised perhaps by the waterblock's restricted flow. The product literature claims 70 liters per hour, which is decidedly on the low side.
