Help: Front Intake fan doesn't seem like it's working

post #1 of 10
Thread Starter 
Lately my temps have gone up a little, and when I put my hand infront of my computer, it seems like there's very little air being move, it doesn't have the same feeling it did a couple days ago, nor is the fan as loud. I put my hand inside to see if it's the same way and once again, there's very little air being moved by the intake fan.

Is there something wrong with the fan? It's spinning at what looks to be a pretty fast pace.

dust filter in front? dust on the blades?

 

what fan is it? how is this fan powered?

 

 

and depending on where you live..... it has been getting warmer lately, which could be why your temps have gone up a little.

Yes, I've taken off the dust fitler, both fans are spinning at about 1000-1100 RPM, I wiped the dust off the blades.

It's a BitFenix 120mm fan, the front fan is connected to a 3 pin cable adapter since my MOBO only has on CHA fan connection on it.

It has been getting warmer and i know room temp has a big play on how hot things get, but my temps are still unusually high. It was 75 degrees last week and I stayed around 30 IDLE, now I'm about 33-34.

Can you please list your full specs? It just helps to know what were working with. smile.gif

Do you know if the fan is plugged into one of the headers on the motherboard? If it is, most fans have an RPM sensor wire that can report the speed of the fan to the motherboard. Using something like HWinfo you should be able to find the speed of the fan and see if it's running normal or not.

Also, if it's plugged into the header on your motherboard, some boards will automatically lower the speed of the fan(s) when the CPU is running cooler. So it might be worth checking in the BIOS to see if any fan speed controls are applied to that fan (like Asus Q-Fan for example).

On the other hand, if it uses a molex connector that plugs into the power supply, it's usually not possible to get the fan speed and the speed won't be throttled back like mentioned above. So the fan could indeed just be wearing out.
Nevermind, I didn't see your post above yet when I wrote this.

don't sweat your idle temps, whats your load temps looking like?

I do worry, it's 5 degrees in a span while the temps outside are cooler. Would you be worried about a 5-7 degree difference?

Sorry, I'm just confused as to why my temps seem to keep rising.

How would I find load temps?

- unless your idle temps are like 60c-70c across the board, it really doesn't matter- especially a 5c gain

 

- my idle cpu temps are 30c-40c on any given day, if i start idling at 45c or even 50c i wouldnt care because again, its just idle temperatures- there are so many non-computer related factors that will affect this.

 

- you never found out your load temps before? serious? go get a benchmarking/stability testing program like prime95, intel burn test, linx or etc and run them. after about 10 minutes or so you'll have your "load temps" 

 

- you thought about reseating your hyper 212? maybe it needs a TIM change? maybe its not seated tight enough? are the fans running properly on the 212?

 

- if you really suspect your intake case fans to be the culprit, upgrade to a higher CFM fan, redo your cable management, lower your cpu vcore, etc.

I agreed what DF is BUSY said.

I read what you posted in your another thread here.

The results sound fine to me.

Look at my rig, it's a Core I5 (non oc) with the Hyper 212+.

The core temps usually hover around 25 - 30C but they can max out around 45C after doing simple tasks such like browsing.
The cpu fan sometimes hover around 500 rpm or 600 rpm.

After gaming a couple of hours the max core temps keep below 50C.

Max core temp under Prime95: 52C - 55C and cpu fan usually spins at 800rpm - 1000rpm.

My case cames with only two stock fans.
My temps were about the same after adding more fans or even max out the fan speed.
