i understand the point of push pull to create more airflow accross the coils and fins to keep the water cooler. now how would i want to do that though? do i want the push to come from out side the case? or inside ? and with the pull do i want to pull air off the rad into the case or do i want to pull it to out side the case?

You can go either way, people on these forums go back and forth about what's better, in or out, but they're about equal, best way to tell is to test both ways yourself. You'll have in mounted on the inside of your case where the rear case fan is, just make sure the fans are both the same and both pointing the same direction, mounting them on the radiator is pretty self explanatory, just screw em into the screw holes. You're basically choosing between blowing colder air from outside of the case onto the radiator, but into the case (and it's warm air when it comes through), or blowing warm-ish air from within the case through the radiator to the outside, which is better for your case temperature, but maybe not ideal for the radiator itself.

I think it all depends on how well your case exhausts the air that is in it. When you have the H50 as intake, it will put a lot of hot air in your case. I have two 140mm fans on the top of my case that pull the hot air out. I also have 1 120 and 1 140 in the front as intake. With my H50 as intake I get between 27c-34c idle on my i5, and under load it's never been past 65c.

Some people report better temps with it as exhaust, and some prefer it the way i do. Best to try it both ways if you're really interested.

Really depends on your case + airflow as to which would be better.

Using it as an intake (drawing air from outside) is optimal for cooling, but you're then exhausting warm air off the radiator into the case.
So long as your setup can handle that (some people need to reverse the fans and redirect airflow to do so), then it will be fine.

Otherwise you can use it as exhaust, and draw air from inside the case to cool the radiator.
Here some people have higher temps because the radiator is pulling warmer air accross the rad to begin with; if you have really good airflow / low ambient temps it should still be fine though.

As said, unless there's a truly obvious choice for your case - try both and see which works best for you

Ok thanks for the heads up guys I'll try it both ways after it gets here. Can't wait to see how much cooler it gets my i3 over the crappy stock cooler. Oh what should I use to clean off thermal paste? Soft rag and rubbing alcohol ?

Isopropyl is good (91% is optimal, but 70% will work too) and a lint-free cloth - if you don't have any of those, coffee filter paper works great

The paste that is on there is some pretty good stuff, so you may want to leave it on there.

Since you have the Challenger, you can do several things:
  • Mount it on the top as intake and have the rear fan exhaust
  • Mount it on the rear as intake and have the top fan exhaust
  • If you have space for it and want to try something different, mount it on the side panel as intake and have the rear/top as exhaust. Your gpu might get in the way though. unless it's mounted towards the bottom.
Intake is almost always better than exhaust (usually a 3-7°C difference depending on setups), but it also brings in more dust unless you have a dust filter.
 
  • Rep+

im leaning towards the top and picking up another fan and running it as exhaust in push pull and then turn both my coolermaster sickleflows on the side in intakes blowing cool air right on the gpu and res/rad

That setup will still run a bit hotter, but it will be leagues better than stock. What I like to do is run intake during the hotter seasons and exhaust during the colder seasons and I just switch during the times I clean the rad and my rig.

Good luck and make sure to post up questions about mounting it if you have any troubles.

One tip when you're mounting the block/pump is to screw each corner little by little, don't screw in one corner all the way when the rest are unscrewed. This could break the mounting and also give you higher temps due to the thermal paste not spreading evenly. Also only put a small amount of paste in the middle, don't bother spreading it evenly. Lastly, you may want to tighten screwing the block as much as you can without bending your board. I once had one corner not screwed in all the way and it made my pump have this annoying buzz and slightly higher load temps.

I'll remember that for when it gets here. Just a little paste in the middle and tighten like you would a car wheel little by little so not to be in even
