Case rattle

[noiseredux]

you can rotate it I believe so you should be alright. Not 100% sure though.

However, turns out the connectors for these (even all the additional ones) are only 3 or 4 pin connectors, and it just so turns out my other fan and only other available connector to the PSU is a 2 pin connector haha...

So I guess this should do the trick?

Err, but maybe not. I still have some molex connectors available from the PSU. I'm still kind of ignorant about cable/power management. The fan is 4 slots, so I need that to a 2 pin male connector if I use the old fan connection.

The motherboard you linked has a 4-pin CPU fan header and two 3-pin fan headers. So, it's safe to assume that two of your case fans are using the two 3-pin headers, and I'm guessing your other two case fans are using 4-pin Molex? Something like one of these...

Et cetera

The one you linked is a Y-splitter for a 4-pin fan header. Don't get this one. You'd have to use your CPU fan header, and it just seems like a better idea not to since there's plenty of adapters available. The one you linked, all it does is steal the power from one to power another fan without PWM. One of the reviewers says, "i just don't know why one of them has 2 pin." That's because you can't split two of those pins, they're used to control the fan speed. That being the case...

I would just get a 4-pin Molex fan adapter, like one of the ones I linked or dozens of similar adapters.

I've never really considered that you can replace CPU fans? Maybe I'll consider that sometime soon, it's getting a little gunky and nasty. I air out my tower from time to time, otherwise seems to be in good shape. Still my baby since this is the first PC I built in 2013 hehe.

Retail CPUs come with a heatsink and fan. So unless your intentionally bought an replacement CPU cooler, you're most likely using the stock HSF that came with your CPU. Stock HSF usually don't have replaceable fans. The newest Intel coolers certainly don't, being that the fan is built into the mounting bracket.

Ones like noise linked are usually replaceable, they usually use standard fan sizes. However, not that there's a difference between a case fan and a heatsink fan. They're designed for different purposes. Don't use a case fan with a heatsink or vise versa.

Here's the one I have: https://www.amazon.com/Cooler-Master-V8 ... B001KUV2KQ

This is the one I replaced the fan in. The only bad reviews you can find for this cooler is that the fan died. I had mine for years with the fan it came with and never had a problem. The only reason I replaced it is because I was upgrading the CPU and decided I might as well replace the fan since I'll have the cooler out, as it's such a pain in the ass to reinstall.

I wonder if the ram slots would be in the way?

You usually don't have to worry about RAM. Most motherboards are laid out with the RAM in more or less the same location in relation to the CPU socket. I say "usually" because not all coolers and motherboard are the same, and some RAM sticks have ridiculous heatsinks. What you really have to watch out for is the HIEGHT of the cooler, and if it'll fit in your case. I have a decent size mid-tower and my V8 cooler barely fits. Just look at the pic of the V8 installed on a mobo (in the Amazon link above). Look at how ridiculously tall that thing is! Honestly, I didn't realize how big it was when I was buying it, I might not have bought it if I did.

Yeah, that cooler looks like a monster.

Ordered the molex cables, I have 3 molex connections available so that should work for my new fan.

Good to know all this info though, I'm hoping to build another PC perhaps sometime around the holidays next year. I'll finally have my own single apartment and it will be cool to have a PC for my bedroom and a rig for the living room.

For the record this is my case, pretty boring but it's gotten the job done and had plenty of room for the extra fans and HDD's. Not a big fan of the front, it felt like I was breaking it when I put the two front fans in...

I definitely want to be a little fancier with my next build though haha.

Got the cables I needed and new fan works like a charm. It feels like it's working twice as hard as my 140 fan next to it haha, but I can't even see the thing spinning. Definitely worth it.
