Corsair CX600M PSU Question.

This is the power supply I am using and this PC has been nothing but bad luck from the start, with issues going wrong left and right it feels like.

So this is the latest question I need some advice on.

I heard a low vibrational noise in the case that becomes louder as the PC runs, to the point where I can clearly hear it. Now, it still isn't roaring-ly loud or anything, music can drown it out easily but the problem is, after listening around in the case, I've determined it's coming from the PSU.

It sounds to me like the fan is shaking about in there, so I haven't pulled it out to look at it because I hadn't realized that was an option until I came online to begin looking up what my options are.

I may just need to tighten it since I can now see it is secured by screws from the OUTSIDE, not the inside. But I figured, I may as well get the question out of the way now so I know in advance, when I contact Corsair tomorrow if I have to and if I even can with the holiday rush in effect.

Can those fans be replaced? If Corsair sent me a new one, is it possible to remove that fan easily and replace it with a new one from Corsair, or am I going to be facing RMAing the entire PSU over this fan?

If the fan is remove-able via those screws I see, is it plugged into the unit inside somewhere, or is it hard-wired into the unit? I've never encountered this issue before, so I have no prior experience.

If anyone knows the answers to my questions, that would be great but I understand it's somewhat of a specific issue and may require someone who's actually messed with these units before.

Fan is not soldered to anything in a psu typically. You can unplug it and install a new one.

Soul Hacker · Dec 21, 2015

Okay, so the 3pin (I'm guessing here) plug is plugged into the PSU internally, somewhere and I'd loosen the screws, lift the fan up, unplug it from wherever it is connected .. remove it entirely, plug the new one in and place the new one into place essentially?

The CX series is not recommended for gaming / enthusiast machines. If you open the PSU, you lose the warranty.

You could just buy the fan and not tell Corsair tho

http://www.techpowerup.com/reviews/Corsair/CX600M/4.html

The cooling fan is provided by Yate Loon, and its model number is D12SM-12 (120 mm, 12 V, 0.3 A, 70.5 CFM, 1650 RPM). It has a sleeve-bearing, so it won't last as long as a ball-bearings fan, but we can't ask for more at this price range.

$6.99 http://www.frozencpu.com/products/10456/fan-688/Yate_Loon_120mm_x_25mm_Fan_-_Open_Chassis_D12SM-12.html

Another option would be grabbing one of these while they are still ridiculously priced

It would be hard to lose a warranty when they sent me the replacement fan to install, don't'cha think? Anyway, buying yet another PSU is out of the question. As I said, the PC has had alot of problems so far and has nearly double'd it's cost in replacing bad parts. I'm out of money to spend on costs like an entirely new PSU.

This PSU will have to do even if they have to RMA it and replace it with a new one but I am hoping they will be able to send a replacement fan instead, since that appears to be the issue.

Clarification: That may be the same fan make and model but it doesn't look like buying the fan and replacing it is going to work due to a difference in how it's mounted. Are you suggesting that is doable?

I don't mind spending another small cost like $6.99 on a replacement fan or something if I have to but I'd rather they agree to send the replacement and retain the warranty if they will agree to that.

JackNaylorPE · Dec 22, 2015

No. Sending you the fan and getting you to open the box actually relives them of having to provide any further warranty support.

I'm not surprised with regard to your difficulties. The CX series is a series of problems waiting to happen.

The issue with the CX series is that they often can not meet the ATX specification, use sleeve bearing fans and the capacitors are kinda weak. Over the years I have seen two threads here where the PSU delivered less than 11.4 volts on the 12v rail.

Well, I doubt my system will be making any high demands but I've had this unit for around 2 months and it appears to be working fine, it's just the fan that appears to be the issue. It's too late to get my money back or do anything like exchange it, so for as long as it lasts, I'm stuck with it but I'm hoping they'll agree to send the new fan since I don't want to RMA it and be without a PC for the weeks that process will take.

I have an older 530W RaidMax here, it's weaker of course and has been used for 6-7 years. I'm also wondering if that unit could supply enough power to hold my system until the RMA is complete, if it comes to that. I don't think I can trust it with how long it's been running already, but if it just needs to buy me a few weeks, maybe it will.

The important thing point I will make to them is if they agree to send a new fan, I will -not- be opening the unit from what I can tell. It depends on where the fan plug is, and their definition of opening it.

I'll be removing some screws, and a plug, not tearing the unit to pieces. But that's purely guessing for me at this point. I don't claim to be an expert on anything, still learning as I go.

The first PC I built, I put it together easily, I turned it on and it worked beautifully and faithfully. The only thing that ever went bad in it, was the graphics card and a friend sent me a replacement he had to spare.

It did have a HDD go bad that forced me prematurely to move to the new one.

But this one has been nothing but problems, it seems like. I'm extremely frustrated at this point.

JackNaylorPE · Dec 22, 2015

Most reputable manufacturers will allow advance shipment. After they approve the RMA, you give them your credit card number. They will get a pre-approval on your CC and ship you the replacement PSU. Once you get it and install it, you use the same box to ship the old one back. The better companies will even pick up return shipping.

Soul Hacker · Dec 22, 2015

Really? I actually thought of asking them about that but I figured the process is always:
- You send them the broken part.
- They confirm it's broken.
- They send a replacement.
- You wait until it arrives.

So I didn't think that would be a workable solution but I had thought like, why not? I was going to ask them: "if I give you my credit card as a 'ransom', will you send me a replacement first and then just charge the card if I fail to mail the old one back to you in 2 weeks?"

If Corsair would do that, that would be great. AMD requires you send the part back to them first, so they can verify the issue personally, but they agreed in my case that would not be necessary, sadly, their warehouse disagreed with them and I just went out and bought a new heatsink rather than argue with them about replacing the stock one which is trash anyway. The phone reps were clear about it, their warehouse kept sending me poorly typed, bad grammar emails telling me they weren't going to do anything.

Fortunately, talking to Corsair on the phone was painless. I had called them earlier about potentially missing some cables, and the rep' was american and was very easy to talk with. So I don't mind calling them and trying to make arrangements.

ASUS on the other hand, their rep was India (nothing against them, just

and there was so much background noise, I kept having to ask him to repeat himself because I couldn't hear him over whoever or whatever was in the background. (sounded like alotta reps sitting in a very small space).

So atleast Corsair isn't like that.

Asus used to be one of the best .... and ya have to wonder why their RMA process and e-mails come from Pegatron (AsRock's parent company)

Look at these picks to see what you have to do to take fan out... cover comes off... it's attached to inside of cover.

http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story5&reid=416

I once rec'd a laptop with a dead CMOS battery. I was offered an RMA return and asked if they could just send me a new battery. They agreed but said that if I opened the bottom of the lappie, I'd lose the warranty. I knew one of the bigwigs there as we had a promotional agreement with the vendor (our 3,000 member professional association got a 8% discount) and he knew me from various hardware forums. He wrote a memo to RMA folks in the company advising that we built desktops for the profession and that I had the "technical expertise" to manage the task of battery replacement .... if ya can believe it, it was easier than on a desktop

In the images you provided, yes, it appears you need to remove the entire cover. However, look at the images provided by Newegg for the unit I actually have. You can clearly see the screws are secured on the outside of the unit, not the inside. So it comes down to where the fan plug is located.

Unless those screws only hold the metal wire-frame in place and not the fan unit itself.

I *may* luck out and just need to tighten those screws, I will explore that tomorrow. I had already turned on the PC and began exploring my options before I realized where the screws for the fan were.

But in the event that that does not solve the issue, and there's a problem with the motor, then I was curious about my options from there.

JackNaylorPE · Dec 22, 2015

As you can see on the CX600M here, it appears that those screws take the top and two sides off... and the fan is secured to the underside of the cover (see upper right and upper left of photo)

Soul Hacker · Dec 22, 2015

Looking closer, there's 2 sets of screws on the 'bottom' of the unit there. It LOOKS like the inner set hold the fan but yeah, now it appears those just hold the wire frame in place. The outter set appear to hold the case panels on. But again, still just guessing.

Well, shit, so much for lucking out on a simple solution, eh?

I'll talk to Corsair tomorrow (If I even can with the holidays and all), and see what they have to say about where we go from here. For now, a loose fan won't kill the unit or cause any problems I can think of, but the noise is troubling since of course, it implies there is a problem incoming even if there is not one right now.

That's of course, working off the assumption it IS the fan but .. I mean, it's a 'knocking' sound .. there can't be anything else in there causing that kinda sound but the fan, I don't think? Heh ..

Thank you both for the replies. They were all appreciated.

JackNaylorPE · Dec 22, 2015

The fan blades could be hitting a wire or something... read the jonnyguru review, they found lots of things awhack on the inside. methinks at this price range, assemblers are given a very short time to complete each unit.

Soul Hacker · Dec 22, 2015

Sorry, didn't expect a response again, so I wandered off. Just kinda glanced at this again outta curiosity. I'll check inside of it when I can, and see what's up but I'll call them in the morning too and ask what they'll offer. Planning on reporting what they say here, too, just in case someone else sees this thread, ya know. The more info, the better, I figure.

Listening to it, though, it doesn't sound like a fan blade hitting something, it sounds motor related. I'll still check when I get a chance, never hurts to look.

I realize this will bump this when it's solved but I wanted to leave an update, if anyone had any questions about Corsair PSU issues, or RMAs.

Corsair has the BEST customer service I've ever seen.

They immediately agreed to Advance RMA a new PSU in ahead of time, saying I could return the faulty one later. They put a "lean" on your credit card, and charge you if you fail to deliver the faulty one in a certain time window. They did not actually charge my card prematurely, just said they would if it came to it which I understand.

Their reps were very patient and helpful.

I had to file a ticket online and then have them upgrade it to an Advance RMA over the phone once their online customer rep agreed to the RMA but they responded to the ticket in 12 hours, even doing so on Christmas Day, confirming it without any hassle.

They paid for 3 Day Express Delivery, but UPS failed to deliver it on time and it took a week + holidays off to finally arrive but the box clearly says Corsair paid for 3 Day Rush Delivery.

I called them this morning, telling them it would be impossible to return the faulty one within the 2 week time window due to how long UPS took to deliver the new one, I was told "No problem!" And they extended the return period to the 18th of this month, which is way more than will be needed to return the faulty one to them.

My new PSU arrived today. Two thumbs WAY up for Corsair. I am going to probably buy from them again in the future, for any parts that I need, that they make. They have come through exceptionally well for me, in my opinion.

JackNaylorPE · Jan 4, 2016

Glad the advance RMA thing worked out. Some manufacturers have been rather snarky in this regard in recent years (are you listening WD ?). With the premium Asus boards (i.e. WS), this is (or at least was) part of the purchase price, no need to give credit card. I reported failure and got replacement board back right away, but it was bent like a banana and I/O section missed the case opening by 3/4". I now was holding two boards and they wouldn't , no matter what i did, send a 2nd board till they got at least one back. Before Halloween, sent it back.... replacement didn't arrive until next calendar year
