this may sound dumb, and may not be the solution to your problem, but i thought i'd throw it out there.

try loosening the 4 retaining screws holding it in. sometimes when those are tight they warp the malleable plastic frame to the case fan, and can cause it to be noisy, usually due to the fan blades coming in contact with some part of them.

failing that, i would think that it's likely a bad bearing, replace the fan with a Thermaltake that has a adjustable fan knob. i used to use on in my main case, that way i could dial it down to match the power supply fan.

Alright just tried to do the 7V mod, but it turns out I have a 3 pin connector. So I'll be looking for a 4 pin 3 pin adapter.

The mod seems like a good way to go for now. Looks quick, cheap, and something good to learn about.

Oh and it's not the fan rattling or anything. It's purely just the noise of air coming out of it and perhaps high rpm. Just the noise you hear when something is spinning fast. A lower speed would help, which is another reason I'm taking the 7V mod route.

Alright question.

I've got a 4pin 3pin adapter, but I don't exactly see how it could work.
I have an idea of how to make it work, but I'd like to ask before I do.

So here's the current setup

Mobo > 3 pin connector > Fan

I bought a 3pin adpater planning to do this setup (which wont work without soddering, which I shall not be doing)

4 pin > 3pin adapter > 3pin fan wire > fan

It won't work because the adapter simply has a female and male 4 pin end, with 3 pin wires jointed into the male end.
So taking out the red and black wires, then switching over the black wire to 5v end wouldn't do anything to the 3pin.

My plan that I ask for approval (lol)

4 pin > 4 pin extension with proper red and black wire switches (male to female end. Basically the adapter with the 3pin wires cut off) > 3pin adapter > 3pin wire to fan > fan

If you need pictures, I perfectly understand and will do my best to get accurate pics.

Is the adapter you have like this one(may or may not have the yellow RPM lead)?

If so, switching the pins according to the guide I posted will give the right results. Instead of running the fan from a 3-pin mobo header you would be running it off a standard 4-pin molex.

This is exactly what mine looks like. The 3 pin adapter only comes off the yellow and adjacent black cable. Which from my understanding is the 12V and 12V ground.

As you can see it comes right off of the male part, which is where I'd plug it in to the PSU's 4pin molex
So I could only switch the female side right? which wouldn't make a difference?

Looks to me like the 3-pin is connected to the female end.

Then my terminology is mistaken. I always figured the male end had the parts that went inside the...well nvm.

Then replace what I "male" with "female" in my posts then haha

just like biology homie. :lol:

male goes in, female receives.

buck's right tho. your terminology is correct, but look closely at the pic. you'll see that the 3-pin connector is wired to the female end. it's a passthrough connector basically. plug power to the female, and if you need to run the power on to something else, you plug the male into another female.

oh yeah, when you see those little 3-pin connectors like that, red = hot, black = ground, yellow = monitoring (for letting the motherboard read the fan RPM's). if it's just red and black it will give you power and work and all, but no monitoring.
