Processor Fan Direction: Should it Blow or Draw Air?

I have a question: should the processor fan blow air or draw air into it?

It is supposed to blow air onto the processor (radiator).

It should blow on the radiator

of course, blow on the processor, but I turned it on in my PC a long time ago and immediately it became much quieter in the room after turning off the light. If I can write this, it means that the processor is still alive. Regards, Tadek

Can you explain this wonderful phenomenon?[/b]

And when the light is on, it probably hums like hell And what's more, you must be terribly cold in the room since your cpu is still alive.

Gentlemen... no exaggeration! The temperature will, of course, be lower than the fan. blows on the fan, but only when there is good ventilation. and an undemanding process is fan reversal. lowers the number of dB. There is air circulation, and that's what it's all about. It is then taken from outside the radiator, flows through the fins and is also cooled. If the equipment does not overheat, this is a good solution!

This is what I ment...

It became quieter for me when... I got divorced

I will venture to answer that apart from silence there is another plus. Similarly to the power supply, the fan pulls dust from the radiator and does not push it between the fins

In my opinion, the difference is negligible, and as for dust, it will be blown in anyway, or rather sucked in (look at the grilles in the computer power supply, dust also settles on the computer side).

The only difference is probably that when drawing air from the radiator, hot air passes through the fan itself.
This may affect its durability. The bearings will probably fail faster. But something for something! Either noise or buy a spare fan.
Using a computer without a CPU cooler is, in my opinion, inelegant.

So I've read it three times and I'm wondering what's going on?!
1) With the processors currently used, there is no question of not cooling the processor (this era ended with the arrival of the 486)
2) What does the airflow direction have to do with the fan's durability?! Air temperature up to 40*C (because it won't go any higher) and the bearings deteriorate faster?!... I don't think so...

Could your friend specify/explain what was going on?

Hmm!!! I thought I wrote clearly that the fan should blow air onto the radiator. If this is not the case - then try to answer the question: at what temperature is dangerous for the fan... GREETINGS!

Well, it wasn't clear to me from your previous post
And as for the safest temperature for the fan... well... I think that what is achieved at home has no impact on the operation... Do you really think that it is whether air at a temperature of 25*C flows through the fan? "less destructive" than air at 40*C - for me there is no difference. The bearings in the fans wear out, which leads to their destruction, and the operating temperature (at least within these limits) has no influence on it!!!

Gentlemen, you are raising a strange problem here, because in my opinion it makes no difference either way, it's just quieter when it blows out and not when it blows in, and now I have a question - should the pump in the toilet first feed the coolant to the coolant or maybe to the cooler and from the cooler to the coolant? ?

Exactly! OK - let's finish this topic!

When it comes to the toilet, it is better if it flows first into the sink and then into the cooler. The point is that the liquid then gets to the cooling element faster, which is almost important in the case of using additional modules for graphics, chipset or disk. The smaller the distance between the heating element and the radiator, the better!

And this or vent. whether he inflates into the process or extracts from it, it matters - if you don't believe it... check it yourself! ...besides...if air extraction was as efficient and quieter...why do all manufacturers do it differently? Could they be wrong??... I don't give away the teddy bears... but that's just my opinion

And I think you're wrong, the circulation is always the same when you have two cooler modules, the flow is always the same regardless of whether the first one is the rotary or the cooler, and besides, it's better to cool it first because then it cools the water and feeds it to the processor, and in in the reverse order, water from the boiler goes to the radiator and goes to the container where there is a pump, and the pump also emits heat

so why is air extracted from the power supplies???

the flow is the same, but the heating elements are different in different places, and it's not about the flow of liquid, it's about dissipating heat as quickly as possible, and the order of connections is important, especially when several blocks are used. (this conversation has gone off topic)

so why is air extracted from the power supplies???

1) because the power supplies have a different design
2) because they do not require as good cooling as CPUs
3) high-class power supplies have 2 fans, one of which pushes air inside
4) it's about air circulation - the back of the case - the air is pushed out, and the power supply is always at the back
