NVIDIA RTX 50 SERIES - Technical/General Discussion

[CornyOC]

What is your ambient case temps and gpu temperature? With my Zotac Solid 5090 no matter what I tried with a afterburner custom curve I could not get it to stay fan-stopped at any higher temp than 55C/56C or so. Without firmware mode it lower bounds you at 30% so there is no fan-stop, with firmware control you can get fan-stop working but the fan still turns on at 55-56Cish even if you've set it to turn on at a bit higher on the curve.

Now I can see some people having a case ambient temp which allows the gpu to stay under 55-56c under light usage like videos. Unfortunately that isn't my case, it has more limited airflow. I set my case fans quite low too as I don't like too much noise if I'm just working and don't have headphones on.

I don't have a sensor for case temp, only components and they are all subject to change. My GPU fans will start rolling at 52C no matter what. Not that it's a problem though.
Remember it's only a PCB sensor, you really want to keep the GPU die cool and have no idea what temp that is, because Nvidia had a great idea to remove the most important sensor.
I had GPU that were around 50C on the PCB but pushing 100C at the die, so I wouldn't recommend keeping the fans at 0 RPM when the PCB is above 50C.
I'd assume fan control is down to VBIOS to an extent even if you take over fan curve with third party apps. Probably your card will start up fans at a certain temp reading, and so does mine.

What I meant was I didn't have sync problem with RPM fans. I don't have much deviation between GPU fan RPMs, and all of them start and stop simultaneously.

Well as already mentioned the default by Zotac is it ramps on at 55C regardless(ie with or without a custom curve unless you set it lower like you have I suppose), and I've just left it on the default for now. I doubt they'd set that if they thought part of it was running at 100C. The 5090 was not mentioned in the hotspot issue by Igors Labs, only the 5080 and below.

But anyway, as I said initially, the real issue is 30% being 1300RPM. I've no issue with having fans on, just not that loud when it's seriously not necessary, and we have no control over that since Nvidia blocks out control between 1-30%.

That "hotspot" issue is about the some components near power phases allegedly going over 100C whilst the die being within safe operating temps. The 'hotspot' normally refers to the die hottest point over the whole area on the die, but they use the term in that article to describe a random hotspot on the PCB that isn't part of the die.
When I said hotspot over 100C, I meant the die going too hot.

When my 5090 is 'dormant' the GPU temp reading is below 40C, so it's not an issue for me as the fans only operate when the GPU runs games. 30% fan speed in my case is around 1200 RPM though.

I got this card last week - also my first zotac. I have been pleasantly suprised - good temps, no coil whine and pretty quiet

Very nice to hear! And I assume it's pretty fast.

Has anyone had any melting connecters getting the urge to gwt one again any black screens?dobt want to buy one and find it has problems ..

@Sc00p007 still waiting on the heatkiller for the palit 5090?

The difference here seems to be your case is much cooler then if your GPU is sitting at 50C idle, I presume you have more airflow/fans, and/or are using water cooling on your CPU (so less heat in the case). Unfortunately I don't have too much choices when it comes to cases because everyone decided to drop the 5.25" drive bay outside of some rare exceptions, and the ones that do aren't usually the fantastic airflow ones. I'm still running a bluray drive, so it's still needed.

Sure am, these delays have cost me pre ordered the Heatkiller, after a few weeks thought, hmmm maybe add a new rad as my setup was a little loud last summer. Rad arrives, block gets delayed. Hmmm maybe a new fan controller, and maybe swap a d5 for apex vpp. Then a week or two pass and i'm swapping out my fans
Really hope the block is ready Monday, but Watercool haven't replied in their Reddit to people asking if it is on schedule. So, i'm guessing they haven't landed yet, as they have replied to other posts.

Yea my rig normally runs an open loop, but I am still waiting for the GPU waterblock to arrive. I have removed the HDD bay long time ago. Perhaps you could make a picture of your case internal arrangement and we could give you some tips to improve.

When I ordered the waterblock from Alphacool it was flagged as 8-9 days wait time (once manufacturing begins in April), that changed to 2-3 weeks a week after order.
It's been approx 5 weeks since and they are still making up for the queue. We are phasing into one paper launch after another, we are getting the real Nvidia experience full package.
That air cooled GPU sticking out in my case whilst I got a full open loop cooling everything else is giving me the cringe every time I look at my rig.

I just completely caved and ordered the alphacool block to arrive Tuesday from a UK site. The alphacool website has it at 3-4 months away and I am fully predicting another heatkiller delay on Monday. Hope not though! Will return the alphacool if it looks like heatkiller sort it out.

Well, I don't think there is much improvement to be had. It's already cable managed using the grommets in the case as much as it can be. I still have 4 SSDs(alongside the aforementioned bluray drive), two of which are behind the motherboard on the case backplate, and the other two are in the bottom two drive bay slots to the side of the psu shroud, so there's more cabling to manage than most people I'd wager but they're on locations they shouldn't be blocking airflow much. It's just physical limitations when you have a air cooled CPU, in a case which doesn't have too much mesh (FD Define R6) and I personally don't like fan noise too much so I run lower case fan speeds until the CPU temps go up.

The only real improvements I see is adding fans to the top of the case, but they didn't include any top with some kind of filter or mesh, only a metal plate to attach fans or a rad to. Plus I like to put things ontop of the case anyway, like if I've got an external hd connected or w/e. So it's not an ideal solution, which is why I've never done it.

But as I said at the start, I'm not really personally worried about temps of the die. It's not great that they removed the sensor, but I do get the logic that with the board now being more compact, the board sensor is likely going to have less of a delta against the gpu die. I don't think Zotac would have set the curve that they did if it was a problem the GPU being 55C before the fan turns on.

Putting a fan ontop of the GPU has mostly stopped the gpu fans from ramping up randomly (and pushed it a bit cooler across all usages), so I'm mostly considering it solved. I just wish that hadn't been necessary and I could have just had the fan always running at a lower RPM around my cards idle/low usage sitting temp.

Edit: On thinking about it, I think there is a mesh/vent for this case I just couldn't seperate it which is why I left it. I'll maybe look into that again.

Update for Alphacool waterblock, I just received a confirmation email from UPS with an ETA of 5 working days. I suppose Alphacool is finally catching up to order queue.

Yea the CPU air cooler will drastically reduce case air flow depending on case size. I run 32x Noctua A12s in my case so the acoustics are quite pleasant for me. The GPU fans sound like a scratchy violin play compared to Noctua A12s.

Your case must be gigantic to fit that many fans in lol. I've mostly just left it to the original configuration the case had which is 2 140mm intake on the front and one 140mm exhaust on the back. Originally I just used the Fractal fans, but they've all had bearings go, one happened within warranty so FD just sent me a new one, but the other two I replaced with Noctua NF-A14 as it happened after the warranty expired.

I just managed to pry off the metal with a knife to reveal the grill/mesh version of the top panel, wasn't easy so I can see why I just left it before (no idea why they made it so hard to get off), so I'll see if that changes anything both thermally and accuoustically as I'm curious. I could add fans there too but I have heard they can negatively impact or not do much for a NH-D15 before. We'll see I suppose.

Fractal pop air has a 5.25" bay and the airflow is excellent. The stock fans aren't the best but you could replace them with something like Phanteks T30 or Arctic P12 ARGB.

Yeah I think that could be an option if I did want to swap cases. I think for now I'm not wanting to spend much more though, so probably going to be a future thought. Already spent way too much with the 5090 itself, haha.

The ASUS TUF OC 5090 averaging 57C after a long session of gaming is just impressive, especially considering the power draw.

I’m glad I removed the sound card so the three bottom case fans can blow straight into the GPU fans.

Nice! Is that with an undervolt, and do you know the typical power draw? Some games pull <400w, even when at 4k max settings, and so it is not a major surprised that such a large heatsink performs well.

do these cards not hit over 600 watts i thought i saw it on youtube.
