HX650 v2 annoying fan curve

Hello,

I recently built my new gaming PC which includes the HX650 v2 as PSU. To my disappointment the fan of the PSU is making an annoying noise, the fan goes from standing still to spinning at a high RPM rate each 15 seconds. It spins at this rate in about 5 seconds and during that time it's the loudest part in my PC by far. Is the temperature controller broken or is this normal behaviour? I would rather have the fan going constantely at a low RPM than going from standing still a high RPM rate in these intervals.

Best regards

Hi, thanks for the reply. I haven't put my system in heavy load yet because I wanted to check if the behaviour was normal. My fan is not running in idle the first 30-50 minutes but after that the whole on and off procedure begins. As mentioned I haven't put my system under load yet, just seen videoclips in VLC and browsing the web with a maximum of 3 tabs open at the same time. Should I test what happens under load or how should I procede?

Best regards

Okay, how do I submit an RMA ticket? Do I contact the reseller or Corsair about this?

I've only had it for a week so I'll contact the reseller. Thanks for the help!

Yep that's the problem I got too.

Hello again!

After a long while waiting on the RMA process to end I got my money back for the PSU and bought a new one for two days ago. To my disappointment the new PSU behaves the exact same way. I'm quite astonished by this since Kalium too did get two faulty PSU's... Luckily I bought the PSU in a physical store this time, should I just submit an RMA again?

I created a ticket moments ago on the website but I was directed to "ask a question" so I haven't got an RMA number yet. But I'll get back to you as soon as I got one.

Hi again!

I thought I should give you guys an update. I got my new PSU today, the shipping went very fast and I didn't have to pay anything for the freight as Greybeard promised. I've mounted it in my computer but to my disappointment the new PSU behaves like the old ones with the fan standing still then starts to spin in specific intervals. The difference is that the fan is not standing still for the first 15-20 minutes like with the old ones. It starts spinning in the same intervals as before but in a lower RPM than the old ones if the PC is in idle and then in a higher RPM if I start to browse the web. So the new PSU I got isn't as noisy as my last ones but it doesn't seem to work as intended.

On the website it says that the fan should not spin until the system reaches 40% load but with my PSU the fan never stand entirely still when it's in idle. When my system is in idle (just running Windows 7 and no extra programs) it consumes 50W, measured with a Voltcraft Energy Monitor 3000 (the same one Sweclockers' staff use for their power measurements) and that's less than 8%. So to my conclusion the new PSU I got seems to be faulty as well, am I correct?

Okay, yeah the noise isn't as bad as before, now it sounds like a fan should do which my earlier ones did not and I can live with that.

I also want to thank you for your support Greybeard, the customer service has been really good and the situation was handled in a professional manner!

I also think it's great that your company is represented here at Sweclockers which opens up for quick responses and makes it easy for both me and others to follow up the process.

Cheers!

I have another question, should the fan make a creaking sound? It sounds a bit like a moped in the distant.

You can hear it in the clip Kalium posted: http://www.youtube.com/watch?v=_iHnrLzScec

At 1:00 to 1:07 and 1:22 to 1:26.

Yes I have a video here: http://www.youtube.com/watch?v=vFgO5Gl3h4k&feature=youtu.be
I put together two sequences where the fan started to run and cut out the parts where it stood still.
I've never heard a fan sound like that so that's the reason i wondered but it's probably not something abnormal.

Since you don't hear it it's probably as I thought, not something unnatural.
