Corsair H50, are additional fans better?

Slinkie · 16 Mar 2010 at 10:36

Hi Folks,

I have a h50 cooling my i5 750. I am using the stock fan that came with the h50 at the moment blowing air out of the back of the case. I am fairly happy with my temps and can run at 4ghz at about 75 deg. However, I think this chip is capable of a lot more as I've voltage to spare but upping it any more increases the temps massively.

What I want to know is if it is worth getting a pair of fans and running push/pull on the rad and if this will increase the performance. I am looking at around £20 for a couple of good fans so want to reduce temps by a lot. I would'n tbe happy if spending this money only reduced the temps by 1-2 degs.

What are your experiences of doing this?

Also, I guess I'd need additional screws to attach the second fan, can I buy these seperately?

I purchased two noctua NF-P14 fans that I put on my H50 and it seems to work pretty well. I too have an i5 750 but I can't honestly remember the temps before, so I can't really say if it made a huge difference although I know there was some change.

switch it so the fan pulls air from outisde the case, will drop a few deg like that also because its not using the warm incase air

The problem I have with this is that it would be drawing in the air from my psu? the psu exhaust is at the bottom of my case

I actually had a similar problem with using a HD 5870, as it sat directly underneath and put all its warm rising air directly in the path of it.

Good point, I have my 5850 directly underneath it as well as the PSU.

Especially when you consider that the GPU won't be putting out heat when testing the CPU. I do wonder if it actually would be better off using internal air when you have the GPU and PSU exhausting heat directly underneath?

Not if you dont have any other exhaust it wont.

I have two Noctua P12 in push pull exhausting air, it dropped temperatures about 10c from a akasa fan blowing over the radiator and Noctua exhausting. I imagine if you swap the corsair with 2 Noctuas it will drop temps about 15c.

I got mine for about £8 each. What cpu have you got?

I tried turning the fans around so they are intaking and i could hear my graphics card fan increasing as prime95 was on. At the moment i have a 120mm fan strapped to the hard drive rack blowing over the graphics card (8800GT) then the Noctuas exhausting.

The 8800 is also clocked from 600/900 to 720/1020

I changed mine from 2 apache blacks in push/pull exhausting to a single sythe gentle typhoon 1850rpm as intake, which has a much higher static pressure rating.

The reason for the change was I had to turn off my top exhaust because it was actually raising the temp of the cpu when on (disrupting airlow) and I didn't want my only exhaust for what is already a hot case to be through the cpu rad.

Now, I have the top exhaust (apache black) sucking out all the hot air from the rad straight away as well as hot air from the rest of the case. I put an Ultra kaze (38mm deep) fan as my intake which I can put on max when gaming (massive CFM and static pressure). i then have an apache black right near the air intake of my gtx280 (this has took the temps down by 5 degrees at load) and then 2 more apache blacks blowing over the top of the gtx 280 and gts250.

The internal apache blacks are so quiet I can have them on full, the top exhaust I can hear a bit so it, along with the ultra kaze intake, get turned down so they cant be heard. The GTS250 fan, which is noisy even at 14%, is et to 0% cause the 2 apache blacks cool it so well. cpu set to voltage auto so its very low at idle. a very quiet case but lots of airflow possible when needed

So really, depends on the rest of your setup. I find it works much better this way.

Mine has dropped 5c running apache blacks

Edit:

forgot to say that is at tick over

I'm using 2x Scythe Kaze Jyuni 1900RPM fans (on fan controller) to replace the single fan that comes with the H50, I have it running push and pull blowing air out of my Antec 900 and it runs my overclocked Q9550 3.8ghz at 51c running prime. I think it depends a lot of airflow/temp in your case.
