Hi all,

I've currently got the h100 with stock fans setup to factory specs blowing air in over the rad (which I understand, cool air in from outside over the rad into the case fore more convection cooling).

However have 4 thermaltake cougar fans coming soon and am going to a push pull setup for hopefully a quieter cooler situation (thought I think the GPU's make more noise so this is probably a waste of money, but hey they look cool).

Now my questions are thus:

1.) anyone played around with the direction on this setup - Do you have your cooling blowing in or out? Did you see much temp difference?

I think I am going to keep it going in as there is a 120mm fan extracting out the back of the case right by it

2.) space for installation anyone managed to successfully drop this or another rad setup into a HAFX case and still have the top fans (200mm ones) in place?

Haven't had chance to try it but the motherboard power cable looks like it's going to be tight with just the new underside fans let alone if I drop the whole top and rad and new bottom fans inside the fram and have the 200mm ontop.

3.) Lastly if I were to fit the push pull inside the case with the 200mm ontop, any thoughts on making them the exhaust and turning the 120 rear fan around?

It's a cold garage conversion room, so other than the middle of summer air in here is closer to outside than rest of the house.

Thanks,

James.
 
Where have you mounted the rad, if at the top of the case... I would recommend using it as an exhaust instead of an intake (heat rises, so the fans will be fighting convection constantly)
 
Keep them as intake presuming you already have 1 other intake and 1 other exhaust.

This way you will have positive case pressure and will really reduce the amount of dust getting in. If you have more exhausts and therefore negative pressure the inside of your case will become a dust magnet.

Me too, I imagine the H100 would be dumping a large amount of heat into the case with the fans as intakes.
 
I've found that blowing the warm air from my case through the rad did not give good results. Having an exhaust fan at the top of the case (as I believe you do), setting the rad as an intake reduce the cpu temp and had no real effect on the temp in my case. Or maybe my setup is fubar :rolleyes:
 
since you're using a new style cooler comparatively:

Assuming the h100 is in the roof, set the fans to exhaust out, set the rear case fan to intake.
..unless you're using a ref style blower gpu? then keep as exhaust I guess..

That's what I'd do.

And yes, push/pull on a h100 isn't worth it.

Try to keep more filtered air going in than exhausting out of the case.
 
close voting 3 out 2 in, thanks for your comments all. Anyone got any Delta's on their set-ups?

Ripshod your right to the fan (sounds like a similar set-up) - what temp difference did you notice when you exhausted through the rad? (Delta to intake)

I've got a 120mm rear top exhaust fan right by it (no air filter so would have to buy 1 if I turned it round) and it's the only exhaust (barring the GFX cards themselves (twin Asus 560Ti's))

Thanks,
 
Got the H100 exhausting out with the 2 standard fans and the phantom has a 200mm in the top helping exhuast, temps are cooler inside the case when pushing out rather than in, its like blowing steam down, it will eventually rise either way.

Thanks for your post,swapped exhaust fans around and the case is a lot cooler.Have been trying all sorts to no avail,so hats off to you my friend
 
Azen. When I made the change I saw a healthy drop of 4C. If you do fix it to the top instead of the rear, as others have said 'best to exhaust'.
 
Cpu is the main temp sensitive device, as such you need it to get the best cooling it can which is going to come from fresh air, just set the remaining case fans to extract none cpu components are rarely a stability issue look to the cpu just make sure there it a hot air way out somewhere.

Your post lacks a very simple understanding of physics. Hot air rises.

Why would you want your CPU cooler constantly fighting physics?

If mounting at the top of the case, the best solution is exhaust.

If at the rear, then it's debatable - but depends on the fan configuration in the rest of your case. In real world use with an H100 on Sandy or Ivy... there would be barely any difference.
 
It's at the top of the case, will flip it to exhaust when the new fans arrive (the corsair manual states to have them blowing in, which I get, blow cold air from the outside over the rad, but do agree with all of you this then has the air meeting hot air from other components rising and the other air being pulled through the case)

Question then is with the h100 on exhaust, should I flip the rear 120 around to import or leave it as exhaust? I have twin 560's which are reference blower cards ( and do exhaust quite a heat beneath the 120 so don't think i'd want to have it sucking that heat back in, but am a begginer/ intermidiate on this so listen to the wise and powerful here :)
 
It depends how dusty your place is, in my opinion.

If you're good at keeping the dust in check, then I would choose to have negative pressure.

If not so good with the dust, I would try for positive pressure... but then this form of cooling will never be as good as the reasonably channelled airflow of in front/out back (or vice versa).

I'm useless with dust... but still go for in front, out back + negative pressure... just need to keep more on top of clearing the dust out of the case.
 
Hmmmmmmm not very good but I would prefer to ahve the better cooling option.

Think I will keep it exhausting (to keep the heat from the GPU's out as well) then jsut have to be proactive in cleaning and the like...

Best laid plans of mice and men.....


(thanks all)
 
I have my h100 with the fans sucking air into the case and through the radiator, a 120mm fan exhausting air out the back of the case and a 120mm fan sucking ait in at the front of the case. Currently my 3770k turboboosts to 4.5ghz (+ 0.05 offset vcore, 1.6 cpu pll volate and 50% llc) My temps are 22 degrees idle and 42 degrees under load.

The way i see it, suck fresh cool air from outside onto radiator and exhaust hot air out the back, rather than exhausting hot internal air through the radiator.
works for me,....

I guess it's what he defines load as, playing games my current setup gets 43-45, however proper load (prime 95) takes it up to 70
