What happens if you stop the fan in the power supply?

Question

Do it yourself

There is an assembly:
motherboard GA-H61M-DS2
Intel Core i3-3220
SSD 120 gb
passive cooling on a fine
power supply unit FinePower DNP-650EPS 600W
I don’t play games, the computer is used exclusively for office tasks + surfing the net.
What happens if you just stop the fan in the PSU? Is there enough passive cooling in it for further work?
I want to get rid of noise completely. A kind of the easiest way to get a silent system :)
When the PSU is overheated, it will simply pass out, or can it lead to more serious consequences?

Answer 1

The power supply will continue to work.
But in the absence of active cooling, it can overheat. As a result, either failure or fire.
You have a low-power system, so there will be no heavy load on the unit, but the problem is that it was designed specifically for active cooling, so overheating is possible even at low load.
Here is an example of a compact PSU with passive cooling.
There are two options -
1) buy a specialized PSU designed for passive cooling.
2) Make fan control depending on the temperature. That is, so that it is constantly turned off, but in the event of an increase in temperature, it turns on.
PS Isn't the power supply too powerful for your load?
Judging by the description of the configuration, you have a maximum peak consumption of no more than 100 watts.
A 600 watt power supply.

Answer 2

As my brother did: He took out
a frozen chicken, put it on the system unit. And then the cooler is not needed, and nothing will explode. In general, there is such a concept, since it is there, then it must be so.

Answer 3

May have more serious consequences. If you want silence, take a power supply that was originally designed for passive cooling, for example:
FOX ATX-400BT 400W

Answer 4

May cause a fire in the office.

Answer 5

We stopped several times in the office ...
Once the computer was slightly buggy, sometimes it rebooted and was hot like a samovar emitting a characteristic smell, but the girls did not notice anything for a week.
Another time, the capacitors simply swelled and the PSU stopped working.
After replacing the PSU in both cases, the computers worked, nothing burned out.
If you turn it off completely, you will need to ventilate the case with something, otherwise the processor will overheat.

Answer 6

You can independently select and replace the cooler / coolers in the power supply with silent counterparts.

Answer 7

It's better not to stop, because at the wrong moment, when it will be necessary to remove excess heat from the PSU, troubles can happen, of which the most harmless is the failure of the PSU.
The noise from the fan is directly proportional to the number of revolutions. The most reasonable way out is to install an automatic reobas, in which the fan without load / at minimum load on the PSU will be stationary, and when the load appears, it will begin to remove heat from the elements at a minimum speed, increasing them if necessary.

Answer 8

Take apart and sort out the fans inside the PC, they are quite the same type and simply disassembled in 95% of cases. You take it apart, clean all the insides with ear sticks or just cotton wool, pour a little fresh oil into the mechanism itself, and voila (!) - everything has become much quieter;)

Answer 9

solder the resistance and it will work quieter and less likely to overheat
