CoolIT Eliminator and Freezone CPU Coolers Review

Cooling/Water Cooling by jmke @ 2007-10-01

These two all-in-one water cooling units from CoolIT provide plug and play performance cooling with help of several TEC elements to keep CPU load temperatures down. We stress test the Eliminator and Freezone models on an overclocked Intel processors to see how they stack up against the competition.

CoolIT Eliminator: Install and Performance

CoolIT Eliminator – Installation

The installation of the water block requires that you remove the motherboard outside the case so you can install the stand offs which correspond with your platform. You’ll need to look in the manual to know which stand offs and which clips to use, the rest is pretty straight forward.

You lay your case on its side and (re)install the motherboard with the stand offs:

Then you put the Eliminator on the HDD bays or PSU area and place the CPU block on the CPU, make sure to test fit the block to see where the water tubes are going once you move the Eliminator unit, to prevent too many unnecessary bends.

The thumbscrews make the installation very straight forward. Next you screw the Eliminator tight inside the case using 120mm fan mounting holes found at the rear of most modern cases:

Once installed the Eliminator lines up nicely with the side panel:

If you don’t have a window in your side panel you’ll miss out on this cool blue LED logo were you see the water in the small reservoir bubble:

If your side panel features a fan or handle you might run into problems getting the panel to fit correctly and you’ll have to improvise a bit.

CoolIT Eliminator – Performance

We stressed the system for several hours and logged the CPU temperatures while changing the Eliminator’s performance settings, going from Medium to High to Low we get the following result chart:

Madshrimps (c)

(1) At the Medium setting the CPU reaches a maximum of 58°C, the wall outlet is reading 177W total usage, that’s 39W more compared to using the Intel stock air cooling.
(2) At High setting the temperature drops to 50°C, the TEC units are being fed more juice and the exhaust fan is spinning faster, total system usage is now at 184W, at 46W we’re not at the theoretical maximum of 56W.
(3) The Low setting made the unit quite silent, with the fan speed dropping a lot, but this results in overheating at 74°C we decided to end the test as the temperature was still rising. Total power usage was only 162W, still 24W more than air cooled.

Onto the big brother, the Freezone ->

the condensation seems troubling. eventhough it only formed with the case open, it's no guarantee it might not happen under certain circumstances with a closed case.
Comment from jmke @ 2007/10/05
it only happened with case open + idle system + at maximum performance setting;

as you can see from the dBA reading, you don't want to have it running at max performance all the time, not good for the ears, as soon as you throttle it back, the Pelts use less energy, less risk for condensation, you work at your PC, every small load will increase temp, no condensation, closed case = forced airflow front>back, less change for condensation.

It all depends on humidity level in the area of use. It's called or similar to pipe sweating -

If you are in hot and humid climate; running at max level with ATX case that has a large screen side panel might have a problem. Naturally, operating such system in North America other than the State of Florida in summer, likelihood might be less.
