mjaafar Posted March 4, 2020 Share Posted March 4, 2020 (edited) Hi I have a HX Series™ HX1000 — 1000 Watt 80 PLUS® PLATINUM Certified Fully Modular PSU (UK) https://www.corsair.com/uk/en/Categories/Products/Power-Supply-Units/hxi-series-2017-config/p/CP-9020139-UK I know this is quite an old PSU, but I recently change my GPU from 2 * Asus GTX980s to 1 * AORUS GeForce RTX™ 2080 Ti 11G And when I has 980s as SLI the PSU, wasn't working as hard and the fan was quiet, but as soon as I replaced them with the single 280 Ti, it suddenly ramped up and became much much louder. Is this normal, because of the new GPU, or is it something I should be concerned about.

Vegan Posted March 4, 2020 Share Posted March 4, 2020 The GTX 2080 Ti can use upwards of 300W of power so it cam definitely cause the PSU fans to activate when in use gaming etc. Link to comment Share on other sites More sharing options...
mjaafar Posted March 4, 2020 Author Share Posted March 4, 2020 Only thing is, it's doing it while idle Is there a software that allows me to monitor the PSU I have, so I can see what it's doing I also took a snapshot of Hardware Monitor of the current stateHWMonitor.txt Link to comment Share on other sites More sharing options...
c-attack Posted March 4, 2020 Share Posted March 4, 2020 (edited) 980 cards were little piggies too so it is likely you use less wattage now with the single Ti capped at 330W vs two moderately loaded 980s. You haven't described your PSU orientation. Is it flipped up and sucking in GPU waste heat? Possible the new card exhausts air directly into the PSU vs a different pattern on the 980 that used the heat pipes. Not sure of your case, but you likely want the PSU fan side down. If the PSU is already fan side down, are there any other contributing factors? Room temp change? From your description, I am inferring this only happens at load. How does the PSU behave at idle or lower standard desktop loads? *No, you have the non "i" version, so there is no software to read it. You could try and get an exhaust temperature reading from the PSU, but that might be difficult without proper tools. How does it feel on your hand? Warm? Or very hot?

Corsair Employee Corsair Notepad Posted March 4, 2020 Corsair Employee Share Posted March 4, 2020 Are you using a single PCIe cable with two 8-pin connectors to power your GPU or are you using two separate PCIe cables to power your GPU? Link to comment Share on other sites More sharing options...
mjaafar Posted March 4, 2020 Author Share Posted March 4, 2020 Thanks you all for the info, and now that I've taken another look, I can't believe I didn't notice it before. because I just realised that the noise is actually coming from the radiator fans of my Corsair Hydro Series H115i Extreme Performance Liquid CPU Cooler and using a sound meter on my phone, it was giving 60db. My apologies for taking up your time for something I should have realised sooner. Thanks again and to answer your question my case is a Phantek Enthoo Pro Tempered Glass Black edition http://www.phanteks.com/Enthoo-Pro-TemperedGlass.html and the PSU is housed in the separate compartment separating from the rest of the case. and it feels cool to the the touch.

c-attack Posted March 4, 2020 Share Posted March 4, 2020 OK, well then it seems like the PSU is in the clear. The H115i you can control through iCUE (or previously Link). Again, changes in ambient temp or GPU waste heat will trigger change. Your coolant temp (H115i temp) is the key variable. You should idle about 4-6C above room temp at idle (not after extended load). You should see a +6C rise under full CPU load, but as much as 10C if there is GPU heat mixed in for things like gaming. You don't have to let the fans do their own thing. You can take control. There is no magic formula like 28C=1000 rpm. Set it to comfortable speeds at idle. You can't cool it down any more than the internal case ambient temp.

mjaafar Posted March 4, 2020 Author Share Posted March 4, 2020 (edited) Well I found what the problem was, somehow when I was installing the 2080ti one of the H115i fan connectors came loose, they're not exactly a tight fit and that was why the fans were running faster than they should. so once I opened my PC again and reconnected it, it's now running as quiet as a mouse. Thanks everyone for your help with this problem, even though it was the wrong problem. This definitely teaches me not to jump to the wrong conclusion.
