H80 installion with haf x help

When you remove the fan from the rear spot on the case you then place the H-80 in that spot with the air flow going out as exaust. On the side of the fan you will see arrows that give you the direction of the air flow so you want the arrows to be pointing towards the outside of the case. You can either put the radiator first with the fan on top or the fan first with the radiator ion top.

have you read the watercooling section? located in my sig. Go over to the closed loop cooler subsection and you'll find a video for installing a hydro series unit in your case.

hope this helps.

edit:
you can have the air exhaust out the case. Simply rotate the fan direction shown in the video.

thanks guys for replaying well i will be using SLI config is it better to let the air go inside and let the top take care as exaust ?

or should i make the h80 fans also as exhaust ?

which would be better ??

please go to the watercooling sticky, located in my sig, and click on the closed loop cooler section. details everything you need to know about setup.

You would be beter off having the rear fan with the radiator as the exaust along with the top fans. The HAF-X case has a huge 200mm fan in the side and a even bigger 230mm fan in the front so those two will be intake. The rear will be exaust and the top 200mm will be exaust also. There is an additional spot on top far a second 200mm fan so that onecould be exaust also if you add that fan since it is optional and doesn't come with the case you have to buy one for that spot.
You end up with the rear and top fans as exaust and the side and front fans as intake.

All motherboard manufacturers make thier motherboards differently , some thick and solid and some thin and easily bendable. What MB do you have ?
Asus and Gigabyte make pretty solid boards that I have seen and while MSI boards are good they are very thin and I have had one of those also.
