Always good tests, thanks Xbitlabs!

300$ is better price. heheheh

1.69V.. that's madness!

This is SPARTA!

Also I think this line in the conclusion should be changed.

"For the first time in our tests a liquid cooling system has managed to outperform an air cooler." it should be a OEM or prebuilt liquid cooling system. I'm pretty sure custom built water cooling system have been beating air coolers for years now.

"Not a very impressive difference, is it? The Reserator XT helps set a CPU temperature higher by less than 100MHz. This can hardly justify the fourfold difference in price. In the Reserator’s noisy mode the frequency gain was only 143MHz (at a voltage of 1.6875V) and I couldn’t increase the CPU clock rate further even when setting a higher voltage. Considering the peak temperature of only 62°C, this must be the CPU’s ceiling rather than a limitation on the cooler’s part. So, the Reserator XT may deliver more impressive results with other CPUs."

I'm sure you know this already but I'll say it anyway. If you want to test the increased overclocking potential of the water cooler, don't test it on a quad. With a quad core overclocking is limited to the lowest common denominator of the four cores.

E4300 @ 3.02GHz (stable speed for all software with U120X. NWN2 crashed while anything else ran fine at 3.2GHz).
w/ Ultra 120X and push/pull 150CFM delta fans, with air ducted from outside case and a lapped CPU+HS = 65C under load.
w/ Zalman Reserator XT = 55C under load.

I've yet to try overclocking further, but the XT is a definite improvement over some of the finest air cooling available. I could be getting better results than many because I'm using Feser1 instead of the Zalman supplied coolant, which is said to be **** poor.

"The Reserator XT helps set a CPU [b]temperature[/b] higher by less than 100MHz."
You mean "frequency".

cool

35-45 dB - that's crazy noice !!!!
Machine not only shall be overlocked, ..but first of all MUST BE QUIET !!!

Noone knows, that for most people liquid cooling solution is not choosen because of overlocking (there are only some crazy fans of it), ..but for people wanting have a quite - not noisy fans computer - ...
this is the truth, ..which cooling systems makers seems not to understand.

It's a great product!I will take it soon!!thx for the information!
