Design and Layout of the QuantaCool MHP
Here we see a picture of the demo unit from QuantaCool. This unit only included the case, power supply, and cooling solution. We installed our ASUS Z97-WS workstation motherboard and 4770K processor for our tests.
The case QuantaCool used for this is a Cooler Master HAF 935, which includes a Stacker 915 to house the radiator. This case works very well for this because the Stacker section can be moved to a higher position, if desired. Several different case styles like CaseLabs or Thermaltake Core series would be excellent choices as well. For this picture, we unplugged many power cables to get a cleaner view of the insides.
At the top of the case in the Stacker 915 compartment, we can see the radiator used in this setup. This is not a radiator that would be used in a water cooling setup, it is a HVAC type radiator. The size of this radiator is what we would call a single rad type; it fits a standard 120mm fan. The fan they used is a 125 CFM Delta which is powerful, you could also use two fans in a push pull configuration with lower CFM also. For our tests, this fan is plugged into the CPU fan header and controlled in the BIOS. We left the controls on auto for our tests. This allowed the fan to operate at a lower speed when idle to lower fan noise, it would spin up to full speed under loads.
We asked QuantaCool if using a larger radiator would have an effect on cooling, and we were told that in this type of setup the effect would be small. Moving the radiator to a higher location would have a bigger effect of cooling than going to a larger radiator. However, a larger radiator would allow the use of dual low-speed fans (to maintain total cooling airflow), which would make it much more quiet at full load.
Here we can see the cooling block that is used. At this time, we had a hold down that was 3D printed to use for our setup. This works just fine for our testing purposes, however, a metal hold down would be stronger and allow a tighter fit to the CPU itself. QuantaCool told us that several cooling blocks can be installed in parallel from a common radiator, e.g. for dual-CPU set-ups, or to cool a GPU. They can design cooling blocks for almost any device geometry, and that the blocks can also be installed on the underside of a board.
The picture also shows the use of quick disconnects that can be used for this system; our demo unit did not have these. We also asked QuantaCool about the fittings used for the demo unit. It turns out that some of these fittings can be moved to the Stacker section to free up space in the main computer area. Much of what we see here in this demo unit is for concept demonstration purposes and do not reflect what an actual production cooler would look like. Let us move on to testing the QuantaCool MHP cooling unit.
