Hello, not long ago my computer crashed because it overheated, yet I have water cooling and I wanted to know if I set it up correctly.
I have a Master Lite 3.1 case and a Lepa water cooler (I'll skip the "Lepa is bad" remarks).
So I have the small stock fan at the top left of the PC and the radiator on the right in the front panel with the fans inside.
Is that okay? I wanted to know if I should place the fans behind the radiator to push air directly from the front to the outside instead of having it travel through the PC to the left fan.
Should I buy additional fans to put in front of and behind the radiator?
I want to specify that my case does not allow for a top mount.
Thank you, I'm feeling a bit lost!

Thank you for your response,
Yes, I know that's logical, I just wanted to know if the hot air has to pass through the entire case to be expelled from the back or if I should directly expel the hot air from the front of the case by placing the fans at the back of the radiator, but I don't know which of the two options is the best one.

Hello,
Indeed, if you had overheating issues (and your PC is clean), then there is a problem.
Airflow in a PC case is important since it's the only way to cool your components, and there are some basic rules to follow.
The basic principle is that you need to bring in cool air and exhaust hot air from the case; heat rises (that's the law of physics), so typically, you bring in cool air from the front (and/or bottom) of the case and exhaust it from the back (usually top).
The second point not to overlook is static pressure; indeed, if you're bringing in air, you need to let it out. If you bring in too much or not enough air, compared to what you let out, the air in the case will "stagnate," and the heat will not be expelled as efficiently.
That said, I see that in your photo, your AIO is placed in the front and blows air into the case towards the front, and if your rear fan is also blowing air outside the case, you don’t have any cool air coming in, leading to suboptimal cooling.
Therefore, I would recommend that you reverse the direction of your AIO in the front so that it brings cool air into the case, and your rear fan should be set to exhaust, to push out the hot air.
This way, you will have a good airflow in your case; moreover, your AIO will no longer receive the hot air from the other components in the case, which should greatly improve your temperatures.

Yes, this is what we call "Push-Pull" in the jargon. If you have the space and fans to install, why not? However, the difference you'll notice will be really minimal; a 240 AIO already moves a lot of air. Moreover, you need a radiator that is thick enough for it to be optimal. It's more of a setup that we recommend for AIOs with a single fan (120/140mm), and I don't think it would be very useful in your case.
Not to mention that it's better if you have 4 identical fans that run at the same speed so that the static pressure is balanced.
First, reverse the airflow of your AIO so that it draws air from outside into the case; you should see a good improvement already.

Meaning of a fan:
For me, you should do as he does:
More specifically:
( Short video: https://www.youtube.com/watch?v=VS53eX2Gx5w&feature=youtu.be&t=405 )
To do this, dismantle the two fans from the radiator and place them on the other side of the radiator so that the outside air is drawn in from the front of the case and projected onto the radiator.

Hello
without understanding your explanations, I would say that every fan must exhaust hot air out of the case!

Thank you very much, and if I put 2 fans on each side, I'll place the fans that draw air behind and those that blow out in front.
When I turn on the PC, it turns on and then turns off less than a second later. I thought it was the power supply, so I changed it, but it’s still the same. I don't understand anything; since the crash, I changed the fans, everything is fine, but the PC still won’t turn back on. What should I do?
I had a little epiphany during the night.
It may simply be that your water cooling is defective... If that’s the case, it could be due to two things: the pump not running or a poor bleed.
It’s also possible that the water cooling is improperly seated on the processor. Did you tighten the 4 screws in a cross pattern properly?

look at the body of the fan, the directions of rotation and airflow are engraved
in the photo, we can't see the airflow direction of the bottom fan
'in your place, I would avoid blowing hot air inside a box'

hi
a watercooling unit should not be placed in the front
but at the back or the top
so that the hot air can exit directly without passing through the PC
in your case, you need to reverse the fans
- the rear fan so that it brings in fresh air
- the fans of the watercooling unit so that they expel the hot air
see you later
--
no links on the web page in English, I'm already stealing enough on my own

Or even completely reverse everything
2 fans behind the radiator that draw air from the radiator and send it to the front of the PC
2 fans in front that also draw air from the radiator and send it into the tower, and the one on the left that draws air from the tower and expels it.

I have to admit that I'm having a bit of trouble understanding what you're trying to do.
If you place fans in front of and behind the radiator, it’s either "Push-Pull" or "Pull-Push."
Basically, in any case, your 4 fans must be mounted in the same direction.
To elaborate, if all your fans are expelling air from your radiator, there is no fresh air coming into the radiator to recycle the air, and if all your fans are pulling air into your radiator, the hot air is not "really" expelled.
To keep it simple, look at the airflow diagram in a case, as mentioned earlier in the discussion, and essentially replace the word "case" with "radiator" to understand the principle.

What's the case you bought???
In the case of the image you posted
- the rear fan is turned around and pulls fresh air from behind the case to the inside
- the fans of the water cooling radiator are mounted normally to expel air to the outside at the front
There's no need to add more
you won't be able to add two more on the water cooling (total = 2)

if this is the one, a 120 mm fan at the back; and at the front, three 120 mm fans or two 140 mm fans

install two radiators at the back ???
I only see one location for a 120 mm radiator
for the front, a 220 mm or 240 mm or 360 mm radiator

Yes, that's the one,
I was thinking of making a hole at the top of the PC to add a fan
Because as I said, having just one fan at the top to draw in fresh air seems too little, and the fan that draws in air will therefore be positioned just above the heat exhaust from the power supply.

If your AIO is mounted at the front to draw air from the outside into the case, it is the one providing fresh air, even if the air warms up as it passes through the radiator, it will always be cooler than the air already inside the case.
To recap, in your case, if you have a Cooler MasterBox Lite 3.1:
- 2 fans at the front, your AIO that draws in fresh air
- 1 fan at the back that must expel the hot air to the outside of the case
Your PSU expels its hot air at the back of the case, so indeed it wouldn't be very wise to try to draw air from the back of the case.
You could possibly try to rig a fan at the top of the case, but it’s better if it’s intended to expel hot air upwards, from the inside to the outside of the case; hot air rises and we take in cold air from the bottom, that’s the law of physics.

It would be great if you could make a diagram to recap exactly the layout I need to replicate.
I want to point out that I will be installing 4 fans on the radiator oriented in the same direction for optimal results.
This is also an excuse to add 2 RGB fans to light up my setup, which is not illuminated at all, even though my cable management is neat and it looks beautiful ????.

More seriously, if I have to change the case, this one is catching my eye:

If I return the tower I currently have, I will actually be paying 20€ for the new tower, considering that I will have to take everything apart to reassemble it. So is this economic and physical investment really worth it?

Well, personally, I think it will be less complicated to change your setup into a new case than to fiddle with a hole to add a fan; changing the case seems more appropriate to me.
Besides, with the one you want to get, you have space for water cooling at the top of the case, which would be ideal for cooling.

So the rear fan, I installed it in reverse
I placed the radiators in front of four fans, one in front and one behind the radiator, which all four draw air from the case
I’m not going to change the case after all; I’m waiting for the adapters to connect all of this, and I’ll do a re-edit
I might do some DIY on the PC in the future
Thanks to RedBart, Robs06, old hunchback bison, and Djé56400 with their diagrams that helped me a lot.

Yes, it's the best I can do anyway; I'll keep the topic open to share my results with you.
If it still gets too hot, I will have to face the facts and tell myself that water cooling is not suitable for the case and change it.
It's more due to lack of time than budget that I don't want to transfer everything to another case.

But I have a Lepa water cooler, so for reliability we don't rely on super solid bases; I bought it because it has a very good reputation in terms of value for money.
I understand why you chose this one, however with my i7-4970k (non OC), it was between 45-50°C with the fan that comes with the processor and with my water cooling (Corsair Hydro H60) I'm between 32-38°C. I don't want to push it, but if you haven't overclocked your processor, then there seems to be an issue with your water cooling.
Place the two fans at the front of the radiator (remember to turn them) so that they draw in outside air.
