Is the exhaust fan necessary in this build?

[alanp1995]

Okay so in the picture seen below is my girlfriend's PC, she wanted to get a green LED fan so we got the CM Sickleflow 120mm cooler. Bear in mind that there is no alternative fan laying around for her as an exhaust fan, neither will we buy another one. So my question is, can I remove this outtake/exhaust fan as it's extremely extremely loud? Will the computer still be cool enough? Noting that the only game she plays with a 7970 is Sims 4. I also heard that having an outtake fan depends on the GPU's cooling system... So please enlighten me (or not) as to whether I can take out this fan. Thanks in advance!

is the fan wired straight to 12 volts?

 

if it is, thats the reason its loud rewire it to a 5 volt line then.

i would get another fan just for the sake of better cpu temps.

Otherwise the only air coming into the case will be 80 °C air from the gpu , and that can't be good for cooling the pcu.

To be fair though , you might be able to pull it off.

Never heard in all my PC builds I did about a 12V and 5V line.... It's plugged into the motherboard fan connecter.... The only other place to connect it is to a molex to 3-pin adapter....

if its plugged in a fan connector, go into the bios and make it run slower.

 

i just guessed it was a cheaper case fan, of which a lot just are wired into a molex plug on the +12V side of the plug. its an easy fix to swap those to the +5V side of said plug.

adjust voltage in BIOS to make it run slower

 

sickleflows don't like their voltage being fucked around with though from my experience, they make humming noises. humming noise will be just as annoying as having the fan running at over 9000

 

So I went into the BIOS with the Sickleflow connected to the motherboard fan connecter and saw what is seen in the image below. But then when I flipped the Sickleflow to the adaptor from molex and the front case fan to the motherboard connector, I see the exact same thing in the BIOS.... changed things like min and max fan speed and doesn't change anything. #Confused.

or you could just wire all of the fans straight to the +5V of a molex connector like i did.

 

its a bit of fiddling once, but from then on it just works. nothing less, nothing more. system on -> fan on.

The molex adapter I have has just one connecter, it's a red/black wire.... don't know if that makes a different about the voltages or? Because I seen in the past yellow/black wires and maybe that says something about voltage differences? But anyway, I will keep fiddling around, ye've given me some ideas, thanks

To say my stuff in exhaust fan question. That fan does more to CPU cooling than GPU. While GPU cooler is model which dumps hot air all over the case, so is CPU fan. And its also one to make noise, like all other stock CPU coolers.
