Need 140mm fans for my new Lian Li PC-7HX - PLEASE HELP

post #1 of 34
Thread Starter 
Alright, I have a Lian LI PC-7HX I just bought. They come with two 140mm front fans and I assume that the fans that come with the case are probably not the best out there for cooling. I have 120mm Gentle Typhoons from OCN's group sale a while back, but wasn't sure if I could mount them in the case for starters, and secondly, not sure if it might be better to simply have two nice 140mm intake fans.

I was thinking Noiseblockers to keep things quiet with good airflow. Ideally the fans will not be noisy and push some decent air.

For quietness, Noiseblockers, Be Quiet! Silent Wings 2, and the new Noctua A14/15 are probably the way to go. I use the 120mm versions of Noiseblocker eloops and Silent Wings, and I'm very satisfied with them. I'm extremely picky on noise too.

If you don't need total inaudibility at idle, the Corsairs is a good choice along with Cougars.

If you can mount using 120mm holes, Thermalright 140mm gets my recommendation. Relatively cheap, pushes a ton of air, and almost inaudible (inaudible for most people).

Anyone else?

Go PWM fans on everything.. than use PWM splitter with molex power to run them. Than all your case fans can be controlled by your CPU fan PWM signal from mobo using cooler fan as master. wink.gif

I mean if they dont bother you there is no need to change them, really. 2x 140mm intake @1000rpm should be more than enough for your system.
But Yeah, the noiseblockers are a good choice, altough not exactly cheap.

Cheap and silent:
Enermax TB Silence

High quality: bequiet Silent Wings 2 140 & Noctua A14

And doylls suggestion is not bad either...

But again, if they dont bother you then dont change them smile.gif

Is there really a better fan between silent wings 2, noctua a14, and noiseblockers?

If it is just two fans I don't mind spending the extra money. Do you think it is worth putting them on a fan controller? Or should I really notice? The only other fans in the case will be on the Noctua CPU cooler and the rear 120mm.

Also, do you consider having the 140mm fans a better option than throwing in 120mm GT 2150 fans?

Really think you should go PWM. SW2s and A15s are PWM.

No need for fan controllers, software is the way to go - especially Speedfan.

I mean, like always with fans it depends on personal preference. I would imagine that 2x 120mm fans @2150rpm will be more effective at cooling than 2x 140mm fans @1000rpm, but they will also be louder...^^

With your system you might be fine without any intake fan, therefore i would personally go for quality 140mm fans and run them at ~700-800rpm.

The Noctua A14 and the Silent wings 2 are notch above the Black Silent Pro. Personally i prefer the Silent Wings 2, but they are both as good as it gets.

Is a fan controller worth it? doesnt your board have a few fan connectors you could use to control them, maybe through a y-splitter?
They also come with differentz voltage adapters if you want to run them slower 24/7.

Guess I was under the impression that a hardware fan controller was somehow a good idea, but maybe that is for people who use more than the cpu fans + 3 or 4 other fans. I also know speed fan only works while in the OS and the other time it is just whatever the mobo sets it at.

I will check out those then. And yes, my mobo has several fan connectors and cpu fan connectors. Thus I should have no problem. Although I might need a Y splitter for the Noctua NH-D14 unless it comes with one. Again, maybe speedfan and hardware settings via the mobo is just fine. I also like ease of use, but have never had to set my fans in any of my boards other than in the bios.

So maybe a fan controller is just another one of those things that are overkill.

Or maybe I should get a dual radiator and water cool... lol. Although with the thermals on these newer intel chips, I don't see the need unless you are doing extreme over clocking.
