Fan doesn't start at computer start up 1/3 of the time

[ZackTheBlobFish]

I built my computer about a month ago, and sometimes when I boot er' up she has one fan the just wont start until i slightly move it, be that by taking the side panel off and BARELY touching it to give it a boost or too kinda blow threw the case to start it, kinda like a jump start, it just needs a tiny bit of help then it keeps going all day... Weird... Anyone know why this is happening

Because the bearings are failing, most likely.

If you clean your computer with compressed air, make sure you don't let the fans spin while blowing across them or you could damage the bearings.

Oh ok, but they're brand new fans, they came with the 80 dollar case... Is this normal? I was planning on replacing them anyway but thats kinda weird, I couldnt have damaged them in any way building the computer I'm sure of it...

Maybe make sure that the problem fan isn't screwed down absurdly tight or anything. Loosen the screws holding it to the case and tighten them down little by little until it feels like it's not going anywhere. If there's too much pressure on the fan housing, it could be causing an issue there.

It's hard to solve these kinds of problems on these websites because I can't see and feel the fan for myself.

Also, with the case being $80, they're probably not the highest quality fans. Some of the really high quality fans can be almost $40 by themselves.

Do you know the size (80mm, 92mm, 120mm, 140mm, etc) and RPM?

120 mm pretty crappy RPM they barely cool the case because I have a r9 390 which gets SUPER hot, I'm planning no getting those noctua f12 fans

Are they plugged into the motherboard or the power supply? Also, what's the brand and model of your case?

Also, are there obstructions near the intakes like a hard drive bay?

If nothing is directly blocking the fans, I recommend the Cooler Master Blade Master 120 http://www.newegg.com/Product/Product.aspx?Item=9SIA85V36V6209&cm_re=blade_master_120-_-35-103-069-_-Product but if something is blocking the airflow path, then I would recommend getting a good static pressure fan from the Corsair SP120 series http://www.newegg.com/Product/Product.aspx?Item=N82E16835181027&cm_re=corsair_sp120-_-35-181-027-_-Product

The corsair SP120 will not move air as quickly but they will be able to create pressure in the event of there being an obstruction close to the fan, such as a hard drive cage.

I looked up the Noctua fans you're looking at, and they're focused flow by design... What that means is that they will only blow air directly forward and will not blow more than five or ten degrees to each side, so only things directly in front of them will actually yield any benefit if you use those Noctua fans you had picked out.

Oops ment to reply, not pick as solution, but nothing is obscuring them,t hey are plugged in correctly, the only problem is my computer will overeheat if i dont give them that jumpstart, its weird, maybe the voltages are off? Only one fan has the problem, which isnt the one near the harddrive cage, and it works perfectly fine once it gets going. Case is Corsair 300r windowed

And the noctua fans i think would be fine, I would replace the fan next to my harddrive cage so it would blow cool air directly onto the side of my graphics card, and another to assist the cpu cooler to pull air out of the case by putting it on the top left, which is were the problem fan is.

 

[weberdarren97]

I would put one up front and one on the side as intake, then one on the top and one on the rear as exhaust. If there are already functional fans in any of these locations you could just leave them there and only buy enough to fill the other mount points I mentioned.

And it's okay, everybody presses a wrong button from time to time Lol. I went ahead and unchecked that as the correct answer for you.
