Do you know a way to increase the Speed of the computer Fans

tonschk · 02-28-08, 03:10 PM

Hello ,can you tell me please if you know a way to speed up the computer fans , I bought a few Yate Loon 140mm D14SM 1400RPM to add to my Coolermaster CM690 case,this fans are barely audible but the Airflow is barely enough, to slow down a fan is very easy , just add a electric resistance , thank you very much for your help

If they're plugged into fan headers on you MB, there should be controls in BIOS. If your BIOS is not tweak friendly (eg, Dell), an app like speedfan might do it for you depending on the type of controller used.

If it's not plugged into your MB, I'd first have to ask why?... then if there's a good reason for that, you might want to look at a hardware fan controller.

Unless the fan is designed as variable speed, you can't speed it up beyond its design limit. If the voltage had been lowered in BIOS, that could have caused it to run slower than it should have, and restoring the voltage might speed it back up, but otherwise you'd probably need a faster fan. 1400 RPM on a 140mm fan should be plenty of air volume, just not at high speed. That's a big fan.

Is this a case fan or a CPU fan? Not clear from your request without searching the internet for this fan.

I use to have a pair of Volcano fans huge things where you could turn them up with a switch only problem the higher you turned them up the louder they were, they would get quite loud

I got rid of them after a while cause of the noise.

I installed two at the top of my Coolermaster CM690 ( exhaust ), another at the bottom of the case (intake) and another at the front (intake)

I think is impossible to speed up the fan if the fan have been done to run at a specific speed , is only possible to slow down with a resistance ,but never speed up above its standard speed ,speedfan may be also can slow down but never speed up above the maximum speed capacity of the fan ,I will try to connect one of this fans to the MoBo fan connectors But I tthink is hopeless , thank you for the advice

Dirt and Dust build up over time, its worse if you smoke around your computer.
Your fans may be slow due to accumulated debris.

Pop the case and give it a good cleaning. Make sure you pay attention to the fan shafts, blades, and housing.

A little light oil or silicone spary in the bearing will help too.

I did this on my previous machine and it made a world of difference.

OK I see you are referring to case fans. I also see you have plugged them into the dedicated "fan" connector comming from your power supply. I think these are usually full voltage connectors. Those fans also look clean to me so I doubt they are being slowed down by a lot of dirt. Most case fans that claim to be "quiet" on the package or advertising run purposely at low speed.

My favorite fan is the Thermaltake MadDog MD-TTF-DB-A1357. It's a high speed (4800 RPM) fan with both pot and thermal sensor speed controls. I attach the sensors to my Video card and chipset heat sink. As the demand on my system increases, the fans speed up and they go much faster than typical fans. When I'm at the desktop doing 2D stuf, can't even hear them. When running SH4 they howl. Been using this technique for three years with no heat failure even when over-clocking. Of course my CPU and Vid card have a lot more cooling capacity than it looks in your pic where you have a standard CPU cooler that came with the CPU.

I see one of ur problems, the fans are blowing air thru SMALL holes in the case. If you cut out a hole the same size as your fans airflow, 140mm, you'd see an increase in fan speed an air flow. I did this to my case an there's a vary noticable differeance.... It cuts done on noise too, the fans not working so hard..

gimpy117 · 03-01-08, 12:41 AM

i have a fan controller...

Zantham · 03-01-08, 12:48 AM

You have THREE 140mm fans at 1400rpms in your case... and you have a problem with airflow? I think not! Is something overheating in your computer? Because that would indicate a poor setup of something in your case... a bad heatsink, I notice you have a stock CPU cooler and passive video card? Is these overheating?

3Jane · 03-01-08, 02:01 AM

Zalman coolers for the CPU and card. You can't do better.

Zantham · 03-01-08, 12:09 PM

I've a Thermalright on my 8800GTX, it used to run 75C idle / 95C load on the stock cooling, now it runs 50C idle / 75C load with the Thermalright cooler. Amazing difference!

RedHammer · 03-01-08, 12:19 PM

I recommend a CoolerMaster AeroGate II or III, you get good control of your fans, and they come with sensors that you can attach on various spots in your computer so you can adjust up and down upon own demand.

I have to agree with above statement though. You might want to utterly clean your fans. my Right side topside fan almost stopped because of alot of dust gathering in it. It stopped several times. So I just opened up and cleaned (2 mins of my time.) And done

Sincerely Yours
