fan controllers + fans

[cybermaniac]

hey guys,

im going to be watercooling my new rig, and I think i've opted out on the T-Balancer to do so.

I am thinking of the following (all 120mm):

3x Fans on the Rad

1x Fan for the HDD

Then to get the hot air out, i was thinking of having all fans in the system pulling cold air in to the case apart from the Rad fans which will be pulling air out on top of the case.

Now, my colleague stated that this probably wouldn't have enough air pressure.

so i was thinking of the following (apologies for the pic, was in college and they dont have photoshop here, so paint had to suffice (see attachment):

now, the 4 MAIN fans in the system would be the rad fans and the HDD fan (front blowhole fan), these would be some decent Yate Loon 120x120x25 D12SL-12.

and the rest of the fans would be some resonable, LOW SPEED fans, just to aid airflow, not to cool the system.

now, first off: Would u recommend the low speed airflow helpers to be attached to the mobo and then the decent ones to be attached to a fan controller like the kama master?

or would u recommend a totally different fan setup (eg, maybe scrap the fan above the HDDs, keeping the HDD cage seperate from the mainboard cage (so 2 fans on the HDD section, one in, one out), and one fan in on the mainboard cage/partition pulling cold air into the case and have the 3x rad fans pulling hot air OUT of the case......

I'll be cooling CPU, Mobo (NB, SB, Mosfets), and 1x 8800GT.

everything will be overclocked. See http://forum.overclock3d.net/showthread.php?t=20802 for more details on specs and project plan + log.

Contrary to popular belief the yates aren't that good for pa's due to static pressure (very loosely regurgitating what Marci of Thermochill said on here)…

I was going to launch into a load of stuff and links but I’m at work so I can’t. All I know is when I did my rig at the time q6600 OC’d, 8800gt oc’d and NB after all the calculations and graphs I needed 100cfm fans.

I wanted peace and quiet so I ended up using some 70cfm fans at 19db on a controller…

People always end up doing what they want. I sacrificed a few degs on the temp for some silence.

This is probably the least helpful post I’ve made. What I’m saying is if you do what you plan it will be fine.

Your proposed plan will work fine. Its the same setup im using at the moment. But like Smith said the yate loons are not top choice for static pressure.

would you guys recommend some noctuas for the rad then instead?

also, the reason i was thinking for a fan controller is due to the fact that i could put it on silent fan speed whislt at idle yet id be able to whack it up to full speed when im playing games, encoding, etc etc etc.

i dont mind loudness when im doing something that requires 100% cpu/gpu load, however, if i decided to lets say.........download overnight or whatever it may be, then I could whack the fan speeds down, keep it nice n quiet, and be able to actually get a good night's sleep.

Mr Smith, if you could either add me on msn: modem7@gmail.com or post what you were going to post at another time here, i would be much obliged, as both yourself and llwyd seem to know their shizniz (which is more than i can say for myself).

thx for the response guys.

Something like Noctuas NFP12s or Sharkoon 1000s would be good yea. Plus they wouldnt really need a fan controller as theyre hella quiet already..... couldnt hurt though

[cybermaniac]

would you recommend the sharkoons over the noctuas?

[Mr. Smith]

If I gave a preference now to which fan it would be off the cuff, not backed by research.

I'll try to dig up the links re the pa fan thing but it was some time ago and will take me some time. I'll be on my pc tonight so I'll look...

It was something like use the psu calculator to calculate the TDP to be dissipated by the loop.

Then use this gpm calculator to find out the gpm of your loop.

Then use this graph to see what fans you can get away with using...



Maybe google around a bit but like i said i'll look later
