With the Igloo covering the processor and water flowing through the veins of the cooler, this cooler is by far one of the quietest heat sinks that has been placed on my Intel processor. I ran it through the standard abuse and made sure that the same programs were used in testing the temperatures throughout.
Idle temps are some of the lowest I've seen coming right off a boot up. Big question will be how well it does cooling throughout the day and over time.
Firing up Orthos by Johnny Lee we get the prime95 working on both processors with one program. Now temperature wise we are not doing as well, I did stop everything and recheck to make sure we had a good fit on the processor. I even went and set the CPU fan to full on in the BIOS.
After 57 mins we are staying close to 56 degrees for both processors.
After a good nights rest I re-checked the marks -- the temps are stable at 57 degrees.
It's been 19 hours since I started all of the testing, we are pulling around 56 degrees and maxing out at 57.
After a good 24 hours, it's time to turn off the full force abuse against the processors and let things idle for a while. I was still seeing the temps flip between 56 & 57 degrees.
I do not want to just let the processors sit and do nothing while they are on. I left Folding on when I was not around and using this system. On day 7 I re-did the full load testing to see if over time we have gained or lost anything. At 50% load on the processors we are getting about 45/44 degrees on the processors, something I would want at full load.
After 9 hours of running Orthus once again, we are at 55 degrees.
At this point in time, I turned off any program that were running the processor hard and let it cool down. I poked around online checking my e-mail accounts and then saw that it had cooled down to 37 degrees.
I added the information from the hourly screen shots to my chart of heat sinks for keeping track of all that units that were tested. This test system is DFI infinity 975X/G motherboard with an E6400 processor. The case used for these tests have been the Mozart Tx case from Thermaltake.
Overall, the small form factor of this water cooling heat sink is nice and fits well. It doesn't weigh more than a lot of the air cooling heat sinks already out on the market. For someone that does light loads on the processor and doesn't plan on gaming for long period of times, I would say this would work. For those that constantly are using the system at full loads or over clocking, I would not advise them to use this for cooling as we have gotten some better results with air cooling.
The maintenance that comes with most water cooling kits involve cleaning the water and making sure things are flowing at peak efficiency. It is hard to do as they have sealed and pressurized the water loop. Vizo does claim that the water should not evaporate at high speed and the pump should last at least two years. There is also nothing to check the level or the flow of the water.
Thanks to Vizo for sending over this sample!
