Corsair H50 pushpull/H70 - Exhaust or Intake?

[Boyiee]

So I'm looking into buying either a push/pull H50 setup, or an H70. I'm currently running on air a Tuniq120.

I also have a GTX480 in this case, as well as a possible 2nd one in the near future.

Hence my dilemma. The internet is telling me with it's vast knowledge, that it's almost split down the middle as far as intake or exhaust with this cooler. Some forums say one, some say the other. Corsair says to take the cool air from outside, intake, happy cpu. Hardforum has a few posts as well as overclockers saying Exhaust, even though it's warmer air.

The problem with Intake, even though you would think the air is cooler, is the GPU is putting out some HOT fucking air. Heat rises. Therefore heat from GPU goes up, gets sucked in, hot air through rad of H50/70. gg. The problem with Exhaust, is that the inside of the case might not be "as cool" as the outside, so warmer air going over rad, which isn't much different than my current setup with the Tuniq120. Although it would still be cooler.

Case is an Antec900, 2x 120 intakes in the front HDD bays, 1x 120mm Exhaust out of rear, top 200mm exhaust fan. Currently there is no side fan, I think the 120 from the back will be able to fit on the side when the H50 is put there. The H50 WILL NOT fit in the side.

A 3rd option would be to put a small cardboard box, or some small duct (would cost zero dollars have materials in house) and put it over the gpu exhaust and point it away from the direct rear of the case and maybe run the heat a few feet away (outisde desk entirely even), setup rad as intake that way it would assure the rad would have cool outside air running over it.

I plan to watercool the gpu as mentioned in another thread, so this is only going to be for a few months, but still, what option do you guys recommend?

1. Intake: Pull air from rear of case into rad, even though the gpu exhaust is hot and right there.
2. Exhaust: Push warmer air through rad from inside case, even though it's only marginally better than current big air setup
3. Intake with rerouted gpu exhaust.

The correct answer is #2. If you get a GPU without an exhaust blower, you could consider #1 as an alternative since your case ambient will be higher if the GPU is dumping air into the case.. but even in that scenario you better have a diesel exhaust fan up top if its your only one.

[Boyiee]

That's what I thought. Most videos I found that were showing the h70 off actually had it as an exhaust even though corsair says no.

If I could make option 3 for free, without much labor, and have it look good, would that be the best or just as good? It would really cool off my desk and room to divert my gpu heat to another place, so if I did that which option would you pick, still 2?

Do not use the stock fan that comes with this thing. Get two SanAce fans.

reviews show that the H70 is better then the H50, but only by a few degree's (5c at max). But again, every Celsius counts, its just up to you if its worth the 50$ extra. Last I checked Amazon was cheaper then Newegg and offered free shipping.
One thing I like about my Noctua D14 is the extra push / pull it offers (while minimal to anything but the CPU) for ambient hot air in the case... And a side fan it's a good investment, and cheap.
I'm not that knowledgeable about most comp stuff, but I did a good amount of research when I was considering my CPU heatsink

i picked the h70 up for myself and a friend. we both are using it as an intake.
Idle on a 930 is 27c and full load is 55c.
that is stock...
I picked the h70 up when amazon had it for $92. It is a shame that they are now up over $100.

I havent tried exhaust, if i do ill repost in week or two.

Was thinking gentle typhoons

I thought about h50 but I like the larger rad on h70.

I have been trying to come up with a solution for this for a couple weeks now. I did try using as exhaust on the radiator, but it was a bit high cpu temp than intake, as expected (I only have one fan on the radiator also, so as intake it is push and it is pull as exhaust which puts another variable in there). I wish the lines were longer so you could mount it on the front. I had an idea to come up with a mounting that would let it sit at the back end of the 5.25 drive bays since my case can breathe through the covers, and set up the 2 exhaust fans in the top rear as normal. Haven't come up with a solution yet though. It just seems like everything is in the wrong spot. Mobo needs to have the cpu on the bottom and the cards up top, but thats not gonna happen lol.

Mine is #3 currently, but have the advantage of the 470 dumping most of it's hot air out the back, and both of hte monitor cables provide a little buffer against the h50 fan sucking in hot air directly.

You could always just retube the H50 with longer lines so that it reaches the front of your case, thus being able to use it as intake and not turning your case into a tornado. I just use mine as exhaust though because I was lazy and my 1090T maxes at 44c on load @4GHz anyway. Whenever I take the time to sleeve everything and upgrade my push-pull fans to GTs/SFlexes/SanAces then I'll probably retube it with some clear tubing and replace the liquid. But yeah, I have option 2 and it works fine. Option 1 could work possibly if you reconfigured the side fan to exhaust as well, but it's so low on the case that it wouldn't do very well, and that fan does wonders for the GPU PCBs. Also, I don't know if 900s come with it, but my 1200 has a HDD cage mount for a 120mm that could also possibly work to mount your H50 and still have it as intake. I opted to just put another fan in it and have it blowing directly on my GPU PCBs though. Never hitting 65c with a 470 on air is nice.

[Purrrfect]

You never hit 65 on your 470 with just the side fan blowing on it? Wtf. I have a side fan right on top of mine and the shit still IDLES at 65+.

[Boyiee]

Well the fan that I remove from the back to place my h70 there will be put on the side and will probably be an intake to blow directly onto the 480 pipes. I know I couldn't fit a side fan on the case with my tuniq tower but I should be able to with the h70.

The next question is, since I just came into a lot of money, do I upgrade to a 950/mobo/ram now, order my watercooling setup for my 480 now, idk. Could literally put a new pc together lol.

I've got mine hooked up as intake and setup the rad in the front drive bays of my case (Haf 932 is gigantic and I've only got one DVD drive in there). Really easy to zip tie it if you've got extra space in that area. I would have probably set it up as exhaust if I had to hook up the rad in the rear of my case.

I did a lot of reading up on this before setting mine up and the main consensus was always to try it out both ways yourself. Cases and setups seem to make a big difference on how you should set yours up.

[Boyiee]

If the tubes reach, then from the front as an intake would 100% be the best possible way to have it, so that's going to be my first try. As mentioned, even inside below the cd drive in those bays could work.

Well, I don't have a reference 470. I have this one flashed to a 470. And I didn't mean that I have just the side fan blowing on my card. I have that case-side fan, plus the cage-mounted fan blowing directly on the PCB, and my case has 9 fans in it, so the CFM in general is hueg. The cooler on my card is a great deal cooler than reference 470s though. And also I run it OC'd at 875/1950 overvolted to 1.15v and it's still cold. Love my 1200 and that cooler <3
