Good day. Today I will tell how to modify the cooling system in the power supply. The modification will help monitor the fan and include an alarm in case of failure.

Who cares - welcome under cat.
The Chieftec 80+ series power supplies do not give any rest: both high-powered and powerful, and they pull any hardware, even there are models with the now-fashionable cable management system and fan rotation control.
Stop, and after all such system of regulation of turns can be made and independently, and will work not worse, and overpayments practically any. My old bpshnik pushed the idea of fashion, who served faithfully for 5 years, but collected a lot of dust in his life, and the fan rustles indecently loudly. We will deal with the resuscitation of the old man, and at the same time we modify the cooling system.
For the modification we need:
New Zalman for the experiment:
So, first of all disassemble our power supply. Yes, the fan has become dusty, the speed is falling, the noise is increasing, for cooling, let's face it, not very suitable. I don’t cite the photo of the old fan, because immediately after the removal it was sent to the waste basket.
The replacement candidate is a brand-new 12-centimeter Zalman. I will not go into details of why this particular firm, just for a long time I have been using their products. Perhaps the use of fans and from other companies, the main thing here is a three-prong power system.
Contact locations:
Carefully, with a paper knife, remove the red (+ 5V) and black (GND) cables from the connector. As you noticed, the wiring diagram on the power supply is two-pin, here we connect the new fan with the connector from the old fan. The most important thing is to observe the polarity. For clarity:
In general, the modified cooling system looks like this:
We connect the fan to the power supply unit, and output the remaining tail and connect it to the PWR_FAN connector on the motherboard.
In BIOS, you need to check that the rotational speed is displayed, and set up a warning about fan failure. It should also be noted that PWR_FAN is not regulated manually, but only monitored. However, the speed of rotation depends on the temperature of the processor / chipset.
All modifications are solely your responsibility. The author is not responsible for your actions after reading this article. Thanks for attention. And successful modding!

Assembly
For the modification we need:
- Actually the power supply itself.
- A new fan in size (in my case 120x120x25 mm) with three-pin power.
- Screwdriver.
- Office knife or scalpel.
- A little time and faith in your strength.
