exterior mounting a rad

post #1 of 15
Thread Starter 
I was thinking about something. If I wanted to mount a 360 or 480 rad on the back of my computer case is there a way to mount it flat against the directly against the case without one of those ugly bracket boxes? Also if you have a regular rad do you have to cool it with fans and if so how do you power the fans?

If you mount the rad flat against the case, you can pretty much do the pull config, also if the rad is flat against the case, where will the air come from? the small space between the rad and the case wont allot enough air to pull through, thats why people use brackets so theres at least a lil space

you always need a fan for a rad unless its a passive radiator

you can use fan pin extenders or if you want



or a fan pcb board powered by a molex cbale such as this

and also, depending on your rad, youll need different fans

generally, low fin density rads can accommodate a wide range of high CFM fans, also, fans can be run at a lower speed because air moves past the rad without much "push" therefore, its quieter.

but high fin density fans need fans with high static pressure such as the gentle typhoons, but generally tend to need louder fans but will cool very very well

it really cannot be mounted directly against the PC since the fans need to grab air from somewhere. Thats why those mounting brackets sit a few inches off the case, airflow.

The one's I was looking at it looked like it stuck out sideway's directly parallel to the the back of the case. I was hoping there was a way to mount it flat where the fans would suck air in from the side facing out towards the wall.

well technically you CAN, just as long as the case is cut or perforated where the rad is mounted so the fans have air to grab from somewhere.

Here are pictures I made on MS paint. I know its stupid but it will make it easier to explain.



In this picture this is how it looked like it mounted. Sideways sticking out like a giant stop sign. It works but IMO is fugly as hell.

This is what I was hoping to do. It would lay flat against the back and draw in straight.

It would draw air in from the front (as seen in the picture with the little blue lines).

Where would the air exit the radiator?

Yea I forgot about that and it would be hard to get it to fit. The exaust fan or pci-e slots are going to get in the way.

I externally mounted my 480 without a box. I have an XSPC so I used their external bracket and mounted it sideways in push/pull so the air goes from front to rear. I guess I should explain that I mounted it on the side of the case at the back. I just didn't have room to put the 480 inside the case and I was getting sick of it just sitting on top and using up extra tubing. Also, I've seen some pretty awesome accordion like brackets for mounting a rad externally to the back of a PC. Not sure where to buy them though...
