Heatsink dual fan configuration

<< < (5/5)

MauryG5:
After a few days of testing I realized that with the intake fan, the one mounted in the case, the upper part no longer heats even the little that it heated before after a few hours of use. I connected it directly to the 12 volt of the second 4-pin molex connector that comes out of the power supply for the CPU. Since we have a CPU on the Blackbird, the second connector remains free and usable. The only problem is the noise going at maximum speed in the case of this fan that I had inside. I then purchased a quality fan or a much quieter Noctua NF-A9 and with the possibility of using it at a lower speed but always higher than that which the Blackbird gives when switching the speed after loading the petit boot. I'll mount it later and see how it goes but I'm sure that in this way I have the best solution ever.

MPC7500:
You don't need the maximum spped. The fans are rotating as fast as needed ...

MauryG5:
Yes, I know, when they need to increase their speed, the problem was that by sticking at low speed all the time, they made it warm up a bit in the upper part of the case. Now it does not happen anymore because this fan is more adequate in size and I turn it at a constant average speed and in this way it goes great and makes to dispose of the little heat that was formed before.
