Suck or blow? - Page 2

damien c · 12-10-2014, 08:01

I currently have 2 fans on the front of my case drawing air in, with 4 at the top on my H100i drawing air out, and a the rear fan is also drawing air out.

Both my GPU's draw air from inside the case and blow it out the back, which is why I have the rear fan blowing air out, as I don't want it drawing the hot air in from my graphics cards especially, as they are now working harder than ever with my new 4K monitor.

If you want good fans for just pushing air around your case then look at the Corsair AF fans and if they are noisy, put them on a speed reducer cable or grab some Noctua NF-P12's not cheap but very good fans.

The corsair AF fans are great, recommend.
If you don't want to replace the fans and you find that there is noise generated by fan vibration then I recommend http://www.quietpc.com/afm03b-group?...9fnhoCOJrw_wcB

Just ordered 80 from Japan for £9.00 and they do work very well.

Don't listen to Damien.....his case hovers half an inch off the floor when all the fans are running

If you are looking for quiet fans then have a look here

Just a thought, if your machine had enough connectors for what you need then I think it's aerocool (and maybe some other manufacturers) do temperature controlled fans where the fan itself has a sensor and adjusts as it's needed, opposed to PWM where the motherboard has control. Not sure if they are molex connected or 3 pin.

Over the last 5 or 6 years fan technology has come on in leaps and bounds and it's very refreshing to see the art of moving air moving forward.
I had been out of the build loop for 5 years and the 3 machines I have built over the last month have all been quieter and cooler than what I thought was a quiet cool media centre we have at home. It's made me reevaluate the media centre and that'll be a new build in the next month or so with max airflow and main temps the main goal.

No Rammy it does not, you will see how quiet it is at the next lan.

Also how it doesn't take off or hover, since I only have 7 fans in the pc now compared to my test bench which had 10, and my 900D which had 18, and the pc was always fairly quiet apart from benchmark runs.

Lol, 18 fans. Did it look something like this:

Lol

Wouldn't the PSU require extra fans to deal with the current that lot drew?

18? Now that is impressive.

I currently have about 11 fans (2 fans on my TRUE Spirit 140 CPU heatsink hence the edit), including PSU, HSF and Graphics card fans in my current rig. Generally, I have the philosophy of in at the front and side, out at the back and top. So air comes in cool, goes through the "hot bits" of the PC and goes out hot. Not sure if it works 100% effectively but my GTX 780 peaks at around 65c, and my CPU, clocked at 4.3Ghz currently (An i5 2500K) tops out at 60c on stress tests and much lower in general use.

All of my fans are controllable too though. The case has a fan controller and the main CPU fan has an external controller, the rest are software controlled aside from the PSU which is quiet). In winter/Netflix use I shut off all the fans I can and turn the rest to minimum so my PC is as close to silent as possible.

That's not a benefit. The point of the fan is to cool the motherboard, not itself, so it's the motherboard temperature not the fan's temperature that's important. It's useful (marginally) only if you don't have controllable outputs on your motherboard, but even then a splitter on the CPU output is a better idea.

Not if you had a decent PSU. 80mm fans use 1-2w each.

Ken W · 13-10-2014, 11:52

I have a 140 mm at the front sucking air in and a 100 mm fan on the
Scythe Shuriken Rev B Quiet Low Profile CPU Cooler on a Intel I5-3570K CPU, 120 mm sucking out at the top and a 120 mm at the rear sucking air out and a 90 mm on the video card there is a fan in the PSU but that only coolers the PSU.

CPU 27degrees C, MB 24 degrees C

I think you would need to bolt your computer down with all those fans.

Nope. Computer fans have pathetically low static pressure verses anything that comes close to being able to lift itself, let alone a computer with it.

I'd have thought that by the time you hit more than six case fans water cooling starts to make the most sense?
