Where should the fan blow on the processor


blow, processor

These computer components not only supply air to cool the rest of the device, which is not the most effective method of cooling. The purpose of these apparatuses should be to create air in the interior of the enclosure. That is, cold air should be drawn in and hot air should be expelled.

As we learned earlier, cooling units have one direction of air. This direction is indicated by an arrow. The location of the arrow is the body of the unit. If there is no arrow, the sticker on the motor will help. Usually, the air flow is in the direction of the sticker.

It is better to use more blowing machines to establish. This is to create what is called a vacuum in the interior of the housing. Cold air will be able to enter the case from absolutely any opening.

Question about installing the cooler

During assembly I did not notice that the tower cooler is rotated 180 degrees. I kind of don’t care that the lettering is upside down, but does it play a role? And it wobbles a little, a millimeter in all directions if you move your hand. It’s not critical?

You have the cooler where it should be, but the radiator is upside down. If it’s symmetrical, then whatever.

Then you have the fan where you need it, and the radiator upside down)

Technically the coolers are a turntable. All together CO.

It’s worth working on the clamp, and tighten it if there’s room for it. But the location will not affect the efficiency

two coolers for intake (not including PSU) and at least three for exhaust. On the contrary, it is better to have a preponderance of blowing coolers with filters and 1 less of exhaust cooler (or with less power).

wobble. Tighten the screws. Not critical but it can stabilize the temperature. And if it twists on the axis, but not wobbly, it’s normal. The radiator seems to be symmetrical, so it is not affected by the inscription. Somebody must have put it on the wrong side. Move. it’s a matter of minutes.

It also wobbles a little bit, a millimeter in all directions if you move it by hand. It is not critical? The fact that it is turned is nothing, but if the radiator is “wobbly”, and even by mm. It means you don’t have it tightened properly. Critical if you care even a little bit about good CPU cooling.

It’s blowing upwards? There are also blowing fans in the roof of the case?

Yeah. in the roof, though, only one fan on the two mounting holes, not on the axis of the CPU blowout.

And how is the efficiency? I want to put a tower, also have top fans, I think how would be better to place it.

i5 4670 since 2014, I rarely see the temperature above 60C. I don’t know if local experts will laugh at me, but it’s the most logical position of a cooler. Starting with the location of heat pipes on the CPU layout under the lid and ending with the dust exhaust on top of their case)

I kind of don’t care if the lettering is upside down, but does it play a role? If it doesn’t interfere with the proper installation of the cooler, which it obviously doesn’t. don’t care.

And it wobbles a little, a millimeter in all directions if you move it by hand. It’s not critical? Depends on the attachment. If it wobbles not by itself, but when you loosen it with your hands. For some types of mounts this is normal (spring clamp).

The clamping is really springy, I think I read that for some radics it’s normal. Then I’ll run it and see what the temperature is. But you don’t want to be too tight either.

But I don’t want to tighten too much either. And don’t. This, firstly, does not help, and secondly, you can break it.

It doesn’t matter, as long as it doesn’t rattle. The wire can be tied together with a cable tie.

It works? Don’t touch it! (c) (The Zero Commandment of Sysadmins)

I would tighten it tighter if possible. or else it’ll be like this. on your crystal to jump)

It shouldn’t wobble. The fan should be blowing back normally. If a video card heatsink doesn’t interfere with it, then whatever, although I would put it further away from the video card, but if it’s not too hot, then whatever, yeah.

The point is, the fans themselves have arrows, one up (should look up) second left, should look exactly left, more precisely, should INPUT air into the radiator if to the right of the radiator, and blow out if to the left. This is due to the peculiarities of cooling in a closed chassis (system unit) Ideally, have two coolers for air intake (not including the power supply) and at least 3 for air exhaust (not including the cooler on the processor) And then begins dancing. If your video card is obviously more powerful than your CPU, then it’s better to have 3 on air blowing, if vice versa, then on blowing. But the system must always have good air flow, BUT with the lid closed, otherwise the stale warm air warms other elements, and this is not good

How do I know if my graphics card is more powerful than my CPU??

We are talking about cooling. There is however a nuance that together cooling will be very different. For example the processor will have one cooler. The video card has three, and with a RPM of 3.5,000 each.

You can’t compare coolers head-to-head without considering their size.

Almost all video cards have 90mm coolers, so there is nothing to compare. And if your video card has 3 coolers for 90mm, and the CPU has 1 for 120mm, then you should take a couple more coolers to blow heat away from the video card, which means installing them on the back panel and on top. And at least 1 for intake, that is, put it on the front panel, but its size should ideally be 120, and work (if there is no reboost) on 12v Noise will not add much, but the efficiency will be much more than if you do the opposite

It doesn’t. Wobbly. whatever, as long as you don’t wobble it. If you wobble. then as the thermal paste dries the clamping force will be broken and the temperatures will rise.

The fan on the cooler should blow air through the radiator, thereby cooling it. That is, the fan on the CPU cooler must be blowing towards the CPU.

It is better to install more fans on the blow out than on the blow in to create a semblance of a vacuum inside the case. This effect will cause cold air to flow into the case from any opening. Rear Panel. The power supply fan, located near the back of the case, blows air.

How to Determine Which Side is In/Out? On the side of the frame there is a marking for the direction of airflow with an arrow. If there are no markings, you can tell by the shape of the blades. On the side where they are concave, air is blown out.

Always turn the fans on when it is cooler outside than inside. Always turn off the fans, remove them from the window, and close the windows as soon as the air has cooled in the house. The principle of fans is that there should be an average between day and night temperature in the house.

Choosing new components

Before looking for additional coolers, you should carefully inspect your gadget:

  • Remove the lid of the system unit, decide on the number of places to install additional components.
  • It is also worth taking a look at the motherboard, because that is where all the connectors for parts are located.

Here are a few tips that will help with the choice:

  • It is better to choose devices with the largest suitable size.
  • Give preference to devices with more blades. Such devices are quieter working.
  • When buying, it is worth paying attention to the stickers on the devices, because they indicate the noise level.
  • If your motherboard has connectors with four pins, then it is worth buying a four-wire fan.

If all devices are purchased, then you should be wondering how to properly install coolers in the system unit. Now we will answer this question.

How you can install fans in the computer case

Installation of coolers in the system unit is made according to different schemes. Be sure to familiarize yourself with them before you start, because the wrong placement of these units can do even more damage than the lack of them. You will usually find a pair of slots on your motherboard for cooling. You can use both or only one. Schemes of installation of fans in the computer case will then be as follows:

  • On the backside at the top, opposite the processor.
  • On the front wall.
  • Using Two Fans. Front and Back. It’s a combination of the first two.

You can have either one, but the last one is preferable. Note that using only one fan will affect the air balance in a closed system. So let’s take a look at each option individually.

How to use an intake or exhaust fan and which is more effective?

Hello, dear visitors to my blog! Today we will discuss whether it is better to use an intake or exhaust fan and why. Also, in which case the cooling system works more efficiently and how to figure out where the cooler blows.

You can read about exactly how many fans it is mandatory to have in your system unit case in this post.

If you observe the PC, you can see that the processor and the body of the impeller rotate on the blowing out. This is no coincidence: the main task of the air cooling system is primarily to remove excess warm air, and only if possible it is necessary to ensure the supply of cool air.

It doesn’t matter if you put extra impellers on top of the case or on the bottom, the principles I will describe below are true for any layout.

So, if the cooler works on blow, it creates vacuum inside the chassis. The heated air is pushed out of there by the impeller and the new air is sucked in because of the pressure drop through the technological holes. It is noticed that in this case, there are no obstacles for continuous air circulation, and there will be no problems with cooling.

With this layout, an impeller must be mounted on the back of the case.

If the cooler is blowing in and there is no blowing fan, it creates air overpressure in the case, which prevents its normal circulation and can cause overheating of the PC components. In addition, a lot of dust will be sucked in, so the “insides” of the PC will have to be cleaned often.

Ideally it is best to have 2 coolers: one for blowing out on the back cover and one for sucking in on the front. If you don’t have one, put one on the back of the case.

A legitimate question: how to determine which way the blades will rotate?

The easiest way is to connect the coolers to your power supply or motherboard and see exactly how it works. Naturally, before you find out, you need to remove the side cover to get access to all power connectors.

And there is another way to figure out where the main flow goes where the sticker with the model or name is, that’s where the propellers will blow.

Universal rules for installing PC coolers

I describe my experience of fast and secure attachment. You can do it your way or do it your way.

  • Try on the fan in the place where you plan to install it. Do the mounting holes fit, is there enough wire to connect? Make sure that the cable does not interfere with other components and does not catch in the blades.
  • Use a plastic clamp to tighten the excess wire so that its length matches the distance to the connector.
  • Special screws are required to secure the cooler. If they are not included, you may use plastic cable ties. Some users glue double-sided adhesive tape, but be aware that it can fall off over time due to vibration.

Make all connection work with the system unit de-energized!

Correctly installing the fans in the PC chassis. the top rear fan should be blowing air, and the bottom front fan should be blowing air. Then it will circulate naturally and properly, and the cooling system will work as efficiently as possible.

If you do not know the name of the case, you can independently measure the seating for the cooler and determine the appropriate model. The easiest way to measure the seating surface is between the centers of the mounting holes. Below are the distances between the centers of fixing holes for popular sizes of case coolers.
