BSOD when install water cooling to front of case

[Kiều Phong]

I got a job where is asks for installing water cooling. I bought one and place it to the empty spot in front of the case. When running 3dmark i got BSOD. Is this a bug?

When i tried again but removing the rear case fan and place it there, it works perfectly. Is there any logic behind this?

Are you sure you're connecting the power to the water cooler's pump when you install it?

Yes, pretty sure. I even saw the cooler's fan running. I have checked for cables as well as thermal paste, everything is right just different location and one worked one didn't.

If you've the radiator at the front the hot air will be blown into the case. Radiators belong to the back or top where the hot air will be blown out of the case.

Did you even read your statement and think about that in your head? So let's go over what you said. Everyone that's been through high school science class knows heat rises and cold air is at the bottom. It's basic physics.

So logically if the hottest part of your computer case is at the top, why would you put the radiator at the top in the middle of the hot air where it would artificially gain increased temperatures for your cpu just because it's being there, and subject it to all the hot exhaust air from the computer blowing over it.

Logically the best place for a radiator is either on the back with the back fan sucking in to get colder outside air, or in the front where the outside air is colder, to get outside air sucking over it.

The very best place would be down at the very bottom of the case if the case has a mount for it where the coldest air is.

Putting radiators for a CPU at the top can lead to as much as +5 to +10c load temps on the cpu just because of where you placed it.

I'm no narrowhead who thinks only about CPU temperature, I think about temperature on all components. Blowing warm air into the case makes higher temperature on the other components.

YOU want to tell ME something about physics and science? You even don't understand simple physics. So stay quiet.

(And I know where cold and hot air goes, that's why cold air is blown at bottom / front into the case and sucked out of the case at the backside and top and we have tower cases and not desktop cases except some simple business PCs)

Well if you knew about this, why would you suggest putting a computer radiator in the hottest part of the case then? You're just talking in circles at this point.

Right here you're claiming hot air comes in the front of the case.. some how sucking in fresh outside air is hotter than what's inside the computer. According to your own words.

So front of case always sucking air in instead of blowing air out? I thought it's a matter of how you install your fan with exhaust side either inside or outside? Because I pretty sure I saw the exhaust side of the radiator facing outside not inside. I am not computer expert btw, still learning new things everyday.

This is the proper way to set up fans and airflow in a computer case: https://www.howtogeek.com/wp-content/uploads/2017/04/ideal.png

And you always want your computer's radiators to be in the coolest (blue in that diagram) parts of the case.

Thanks heaps.

It makes sense now.

Sorry for stupid question but should radiator fan intake or exhaust?

The common way is to have fans on radiators in "push pull" where one fan pushes through and the other is flipped to suck out the other side to help air flow through the radiator.
