Cooler Master MasterLiquid Pro 140 and MasterLiquid Lite 240. Optimum fan airflow direction?

[Pan_Melas]

I have recently bought two Cooler Master liquid coolers, a MasterLiquid Pro 140 and a MasterLiquid Lite 240, intending to use them on Intel Xeon X5492 and/or Intel QX9650.

The computer cases (boxes) to be used will be:

A. For the MasterLiquid Pro 140, an older Lian Li all aluminum case (box), model PC-201A is intended to be used. Note: The PC-201 has been one of the most sophisticated large computer cases of Lian Li and the one I own was used as a Home Server PC, which has now become obsolete. But the case is still in excellent condition and it is a pity to let it go unused.

This case has space to put the radiator and fans of the MasterLiquid Pro 140 at its upper front, where the 5.25" bays are located. I have to sacrifice three bays, but this will not be a problem. The only modification required is to replace three front 5.25" covers with Lian Li's BZ-501A 5.25" Bezels, providing the necessary filtered air entrance.

B. For the MasterLiquid 240 Lite an older and discontinued Thermaltake Xaser VI, model VG4000BNS is intended to be used, again a large case, quite impressive at its time, which also provides ample space to build a PC with lots of hardware.

This case provides a side door with large mesh openings, where the radiator and fans of the MasterLiquid 240 Lite can be fitted, with ensured and filtered air entrance.

The same question comes out for both coolers:
What is the optimal air flow mode? A "blow in" or a "blow out" one?

FYI, the first computer box (Lian Li PC-201A) it is designed so that generally the air flow inside it is from its front face towards its back. This calls initially for a "blow in" airflow setup. But I need to be sure if this creates major cooling problems or if it is just irrelevant.

The second computer box (Thermaltake Xaser) makes fitting more difficult, but I think I will manage. The question regarding air flow still remains, though. This box also is designed so, that generally the airflow inside it is from its front face towards its back.

Your advice will be highly appreciated.

Essentially, when adding any fans, keep the airflow flowing from the front to the upper rear.

Thanks, a0406090, for your response.

Yes, this is a well known rule, generally applied for air flow at box internals. However, my question is focused regarding the optimal air flow for the Cooler Master Liquid Cooler Radiators. Certainly, if someone can combine the optimal air flow for these radiators with this general rule, it would be perfect. But I am first of all focusing on the Coolers themselves and then on the box internals.

Surely, this general rule for computer boxes can easily be applied to the first box and cooler (Lian Li PC-201A & MasterLiquid Pro 140), but I need to be sure if the "blow in" mode is also best for the cooler itself.

Opinions?

I'd assume that extraction type out of the case would be optimal for the water cooling, as it would avoid heating up the internal air inside the case.

Well, yes, this seems to be the optimal mode for the case internals.

FYI, according the sketches found in the manual for both coolers, Cooler Master also suggests this kind of air flow, but I wanted to be sure whether this would be optimal for both, the case internals and the coolers themselves. Your opinion seems to coincide with the Cooler Master suggested fan fitting and air flow and this covers my question completely.

Thank you again.
