psu Loud PSU fan noise after replacing GPU

[CristianJaviM]

Hey everyone

 

TL:DR: New GPU, PSU fan goes really loud now on load.  Should I think of replacing my PSU for a new one?

 

I recently switched out my EVGA GTX1060 SC with an EVGA RTX2060 Super XC Ultra; I also switched some chinese brand front intake fans with a couple of Corsair ML140 and adjusted the fan curve accordingly. Yet, while playing and doing some benchmarks on Cinebench, Valley or Heaven, I kept noticing high fan noise coming from my PC, but when there's any load on it. I tried to adjust all the fans on my machine (GPU, CPU, 2 intake fans, 1 exhaust fan) and the noise kept on going.

 

Finally, after opening my tower and checking every fan by ear I noticed that the one that that's ramping up is the one from my PSU (Thermaltake TR 600W).

The thing is, unless I have been blaming the high rev noises to other components beforehand, I never noticed this happening before, and it only happens with any kind of load. If I let my PC be, eventually it goes back down to quiet, but it does takes some time.

 

My question is: should I be worried? Is this a telltale sign that is time to change my PSU?

 

Current setup:

• Ryzen 5 3600 with stock cooler (and PBO enabled)

• EVGA RTX 2060 super XC Ultra with a light overclock

• ASUS TUF B450M Gaming Plus motherboard

• 2x8GB DDR4 3000 ram sticks (HyperX with RBG, forgot the model)

• Thermaltake TR 600W non-certified, since it's kind of old

• 2x Corsair ML140 fans as intake

• 1x upHere 120 led fan as exhaust

• Corsair Spec-01 case

Due to the pandemic and my country of origin, I don't have that many options to replace my PSU, I mostly can get either:

• Corsair CX line (450w to 750w)

• EVGA W and N line (from 500w to 750w), a couple of BQ (from 700w to 850w) and GQ line (650w and 580w)

• One Corsair RM line (1000w, kinda overkill)

• A couple of fancy Asus ROG psu (550w and 800w, kinda expensive)

 

Thanks in advance for any and all help.

have you tried removing any dust you can from your PSU? it could be that when you did your upgrade you shook up all of the dust inside it.

if you would choose to get a new one I d go for the EVGE 700 - 850W if it s not to expensive.

the corsair RM line is a bit over kill indeed

Thanks you for your reply!

 

Yes, that was my first course of action, dusting the fan part of the PSU, but to no avail.  I forgot to mention that sometimes, very occasionally, there was a rattling noise and it came from the PSU as well.

 

Since I looked for answers for my question all over the web, a bunch of helpful guys (chiefly Jon Gerow from Jonnyguru) pointed me out to the best option to replace my PSU and I did: I went with a Corsair CX650 due to it's decent rating for a midrange machine and LLC topology and DC to DC feature that, as I was told, was a pretty good option considering it's a budget PSU.

 

Thanks you all for the help!
