Thanks for the response.

I was actually trying to find a way to avoid mounting the fans with the type of screws you provided a link to since my first attempt ended up breaking the plastic around the mounting holes on the fan.

I'd like to find thumb nuts that fit the end of the screws that are intended to be used for attaching the fans to a radiator.

As an example if you look at the second photo in this link you can see the black round knurled thumb nuts that are used to attach these fans to a case -

The third photo down in this link shows another example -

This indicates that you are cranking them down way too much. Yeah, I know, you want to make sure that everything is secure and going to stay put, but there's a limit--past which, all you get is needless damage. If you are worried that the screws will loosen, put some thread lock on them and just snug them up. It'll be fine.

Way too many people think that a fastener isn't tight enough until it won't turn anymore. Not true.

Actually not at all, the fan screw didn't even make contact with the fan support/bracket before it broke the plastic around the mounting holes.

Actually the SP120's have an issue with this.

In order for the mounts not to break you literally have to screw in a little bit, back off, screw in a little bit more and so on and so forth. Its literally like running a tap through of how small the mounting holes are. So much so that the screws actually get hot.

I've literally just had this exact same thing happen to me!



I just got the double pack SP120's (just arrived today) to install in to my Bitfenix Prodigy case. I opened up my case, held the fan perfectly in line with the holes. I attempted to loosely screw them in to place, but getting them to screw in even the tiniest bit proved to be a mission.

When attempting to screw in the supplied screws, it quickly became apparent that the 'supplied screws' when tightened twisted, stretched, stressed and warped the rubber mounted screw holes on the SP120 fan.

The craziest thing of all was that this wasn't a case of over tightening for me, as the screws, which were screwed dead straight in to the correct mount points, began to over tighten way before the fans were anywhere near secure or snug up against my case.


Note, The supplied screws were screwed in perfectly straight, so you can rule out any over tightening theory of any screws being driven in at the wrong angle, again mine were dead straight!.

Also worth pointing out is that my case screw holes are bigger than the thread on the screws supplied by Corsair, so you can also rule out any other complication that can arise from having 'case holes' which are too small for the supplied screws thread. My screw holes on my case are more than adequate!



Anyway, back to what happened....


Obviously leaving the screws half hanging out or half in was not an option that i was prepared to settle with, partly because it would look rubbish and largely because the fans rattled like a car engine with defective engine mounts.

You can guess what happened next; Yep, the exact same thing as the original poster of this thread (i.e El-Skunk). The screw, which weren't even anywhere close to securing my Corsair SP120 to the case, broke in exactly the same way that El_Skunk suggested.

Now I also have part of the mount and screw stuck in the mounting holes in my case, I'm going to have buy some pliers tomorrow to try and prevent the bottom section from spinning while i try to unscrew them.

This is a real shame that this has happened, I can only say that I am really disappointed, especially after waiting over a week for these to be delivered, just to have this happen on the day that they arrived; after time spent pulling my case a part to fit them only to have to remove them and put everything back to scratch, until the time comes again to do it all over again.

No, this is happening way before the screw is even close to the case, you can still see the thread of the screw!

Can anyone tell me the correct way to raise a support ticket regarding this matter to Corsair customer service (UK), please?

In the situation where the grommets start to twist and pull themselves out of the fan housing, I found it very beneficial to get the 4 screws in finger tight, then actual pinch the rubber grommet in place while pushing it against the fan mount, and then then screwing it into place. Another option is to do this outside the case, and get the rubber stretching and partially ready for a screw.

Hi'ya Funtambulus

I appreciate your input but if I wanted a product that required modifications, time or tampering to fit over the simplified usual method of simply screwing in four screws to mount, I would of purchased a $2 cheap imported fan from ebay and done so knowing I had purchased a ridiculously cheap low quality product at a low price and had very low expectations for it. LOL


What I don't appreciate is buying high end expensive brand fan from Corsair, with all singing all dancing noise reducing mounting points that tear, rip and fall apart before you even get to fully mount, tighten or even use them.


I also find it extraordinary that a manufacturer can acknowledge an issue, authorise an RMA and then suggest that WE THE CUSTOMERS foot the postal charges to correct something that their design team's oversight caused.

Default Unofficial AF/SP Series Fan Installation Guide

I had the exact same problem with an AF 120 Fan, where the rubber twisted and the plastic screw hole inside of it broke free from the rubber housing and was just spinning inside. The fan was left stuck to my brand new case. Needless to say, I was not pleased at this point.

To get myself out of that situation, I had to take an x-acto knife and carve away at the rubber surrounding the plastic screw hole. Once it was free from the rubber housing, I took a pair of needle nose locking pliers to the plastic screw hole piece and was able to free the screw from my case.

I think the problem comes from the use of self-threading fan screws. If you look inside the plastic screw holes before installation, they are smooth on the inside with out any pre-drilled screw pattern.

To work around this with the existing fan implementation, this is what I found to work.



Unofficial AF/SP Series Fan Installation Guide

- Following the technique described below, you should be able to successfully install your AF/SP series fans.

Step #1:

Now this 1st step may be overkill, but after getting a fan stuck to my new case and then just barely getting it back off, I wanted to be extra cautious. You can try skipping the 1st step outside the case, but still use the same technique when screwing them to your case/radiator etc. Use your discretion.

Note: Complete this step outside of the case. Put the fan down flat on a desk/table etc.
  1. Pinch the rubber grommet surrounding the screw hole with two fingers (thumb and index fingers). This will ensure the rubber grommet does not twist, and you will be able to feel when it does begin to twist.
  2. Begin to gently thread the screw into to the screw hole, straight with even pressure.
  3. Screw in only 1/4 to 1/2 turn at a time. You will feel the rubber grommet begin to twist. When you feel the rubber grommet begin to twist OR if you feel that the resistance you are meeting when trying to screw into the fan is too much, begin to back the screw out.
  4. Roughly for every 1/4 to 1/2 turn, reverse and turn it back it out as much as 1/4 to 1/2 or more. Then repeat the process, by turning 1/4/ to 1/2, reversing it out etc. You will notice that you are meeting less resistance for the part that you have already threaded. Also, the screw can get a little hot during this time.
  5. Slowly, you will meet less resistance as you get the screw further threaded into the plastic screw hole. This technique will allow you to get the screw fully threaded with the screw head reaching the rubber grommet, without damaging the fan.
  6. Do this for all the screw holes that you intend to use for your installation.
  7. Afterwards, once the screws are removed, you can visually inspect the plastic fan screw holes and will now see that they are threaded.

Step #2

Note: Complete this step using your case, radiator, etc.
  1. Repeat the technique listed in Step #1, but this time screw the fan to your case/radiator etc. You will notice that you will meet similar resistance, like you did when you threaded the plastic screw holes outside of the case. Also, if you can't grip the rubber grommet with your fingers, try to visually see if the rubber grommet is beginning to twist OR feel the resistance on the end of the screw driver and judge when to back it out.
  2. Repeat the technique listed in Step #1, until you have reached the desired tightness.

I hope that this post is useful and can help others.

Added two SP120's to my case and this was also an issue. I ended up just screwing them in as hard as I could until I was sure the screw was going to strip - one of they actually may have done so. Now I have screws sticking out of the bottom of my case and it makes it extremely difficult to attach magnetic fan filters I had to buy since Corsair elected fan filters down there were not a matter of importance. I'll have to give this a shot.

Corsair makes some great stuff... but they are jacking up on little details like this and it is unacceptable.

I agree. Those self-tapping, very coarse threaded screws are the pits and if the plastic is the least bit brittle, it will fracture well before the screw is even close to being installed.

The screwing in/screwing back out and repeating this process little by little did in fact work perfectly for me. My screws are now all the way in without a problem... I only did two of them at opposite corners for both fans. I got tired of the forearm workout and blister that was forming from the amount of pressure I had to use to hold the screw driver.
