Sanyo Denki's San Ace manual.

https://www.sanyodenki.com/archive/document/product/cooling/San_Ace_M0011876.pdf

Not sure what is different about SanyoDenki's design, but BB fans in general use chrome steel balls. Perhaps they are using something more fragile and should be avoided.

That is the main point here.

Regardless, the concerns you're expressing about the type of fan motor bearings used is not a concern you should focus greatly on.

I am not interested, at all, in a contest about who is more of a fan expert. This happens every time fans come up and I was bored of it years ago when I first experienced this phenomenon.

That's an interesting attitude to take when you came here asking for input on a subject you seem to know little about. There's no shame in asking for input and advice. It is however very rude to smammer about with attitude when someone offers input that you have never crossed paths with. Just throwing it out there. It's a kind of foolishness that some don't suffer lightly, myself included.

I posted to provide feedback for the reviewer, W1zzard. Now... please excuse me so I can begin building your statue.

Does the SUPRIM use phase change TIM or just regular thermal paste on the GPU? The card looks great but if it only uses paste I’m concerned that it will pump out very quickly on such a large and power-hungry die. This was an issue on some 4090 cards and replacing the stock paste with PTM would solve it completely.

Normal paste, if you're concerned just replace it with what you prefer, takes 10 minutes. Very easy disassembly

Does this card only have one fuse which is located near the PCI Express motherboard connector near the bottom of the card, or does this card have additional fuses that I have not been able to find? I have been looking at the PCB photos linked from https://www.techpowerup.com/review/msi-geforce-rtx-5090-suprim/5.html and have been only able to find one fuse on the card's front near the PCI Express motherboard connector and the VRM phases. This fuse is labeled "F1". The card's web page advertises "fuses" in the phrase "Additional fuses built into the custom PCB provide additional safeguards against electrical damage." at https://us.msi.com/Graphics-Card/GeForce-RTX-5090-32G-SUPRIM-OC . Also, what do the fuse or fuses protect? As far as I can guess, fuse F1 would prevent the card from overdrawing power from the PCI Express motherboard connector if something shorts out and the fuse is in between the short and the motherboard PCI Express connector.

I am wondering if this could possibly be a translation error because I learned that singularity or plurality is not that strongly typed in Japanese when I tried and failed to learn that language in college, so I am wondering if Chinese could also be not so strongly typed by singularity or plurality as English is and therefore requires context to either determine whether a noun is singular or plural, or if the translator would have to either guess or write a whole bunch of words to explain that the translator cannot determine whether the noun is supposed to be singular or plural.

While that's an interesting set of thoughts, I have a question for you: Why do you care about fuses? The main purpose of a fuse is to protect a circuit from an overload situation and will they blow/trip should it be subjected to one.

If you're really worried about the kinds of problems one would need a fuse for, you should be focusing on a power line conditioner for your home, a quality UPS with solid surge protection for your PC to plug into and a quality PSU for the PC itself. The fuses on the card are quite literally the absolute last thing you should be concerned with when discussing GPU(or any other part within a PC) power delivery.

If you have watched various YouTube channels of repair technicians repairing video cards, you would have seen problems other than power delivery itself that cause fuses to blow like DrMOS stages or VRAM chips that were once good but developed a short circuit, causing a fuse to blow. Had the fuse not blown, the short circuit could have fried more components of the video card or have damaged PC components outside of the video card like the motherboard or power supply unit by overdrawing power from the motherboard PCI Express connector or one of the power input sockets. Buildzoid shows in

how the fuses in an MSI RTX 4090 Suprim X or Suprim Liquid X can protect the video card when something fails. For example, a memory VRM short circuit can fry the GPU chip itself if a fuse does not blow.

Take a look at

to see a video card with a blown fuse get repaired to see that the card developed a short circuit behind the fuse, so the technician replaced the shorted out part and then the fuse.

See

and

to see what repair technicians had to do with video cards that developed short circuits which did much more damage that blown fuses could have stopped.

MSI Says it Won't Have Enough RTX 50 Series GPUs on 30th January Due to Insufficient Supply from NVIDIA​

This time, we have an official confirmation about the RTX 50 series shortage from NVIDIA's board partner, MSI. We have reported recently that several sources have confirmed that there won't be enough RTX 50 series GPUs at the launch time, and this will be particularly serious for the RTX 5090 and RTX 5080 launches.

As we reported previously, this was reportedly due to poor communication between NVIDIA and its board partners. Apparently, most AIBs didn't get enough chips to make their custom editions, and we have heard reports that some retailers have gotten the RTX 5090 in just single digits. In some regions, the RTX 5090 and RTX 5080 prices have soared to the point that they are now at twice the official MSRP.

That was a very interesting response. It doesn't negate the fact that PCB mounted fuses very rarely blow and everything that feeds the GPU power is of MUCH greater concern. PCB mounted fuses are of very little concern. Consider your PSU, UPS/Surge protector more carefully.

So apparently we won't even get the opportunity to spend "30% more for 30% uplift (RTX 5090), or in case of RTX 5080 vs RTX 4080 Super -"about the same for about the same - but with free fake frames and an AI sticker"...

Getting NVIDIA’s RTX 50 Series GPUs At MSRP Would Be A “Surprise”; Team Green Leaves AIB Partners With Slim Margins

Will there be more AIB partners going the EVGA path, trying themselves in something else, or will they just look at their red sales numbers all the while Nvidia will display a record revenue in "Gaming and AI PC"?

 

[CornyOC]

is no one else going to comment on that poverty level PCB on a $2400 GPU? am i the only noticed that MSI is basically selling reference cards like zotac and pny usually do?

I was thinking of getting the Palit 5090 Gamerock OC since it has the same 22 power stages and same mosfets as MSI Suprim SOC. The Palit 5090 looks atrocious but since I plan to slap a waterblock on it that doesn't matter to me. Plus, Watercool has confirmed they will release their new Heatkiller waterblocks for Palit and Gainward 5090s (a top brand waterblock for low tier GPU brands... don't ask me why). Then I have noticed something by comparing PCB pictures of Palit to MSI. Those inductors are nice and square on the MSI Suprim, whereas on Palit they are sitting at all sorts of angles. I also checked the ASUS astral PCB and they are nicer than on Palit PCB but not as neat as MSI Suprim. I also noticed the coating on the Palit rear side appears to be like a cheap paint job, whereas on MSI Suprim it is flat and consistent. So I guess that might be a good idea to spend extra $200 for quailty assembly? It is to me at least (bye bye Heatkiller block ;C ).

Does this card use ball bearing fans or FDB?

Do you agree with Lex's claim, which basically contradicts everything Noctua has said since the beginning of time? (The claim being that ball bearing fans are in no significant way inferior to FDB fans, even if they require people to clean and lubricate them after some unknown period of time.)

Also, do they become louder with time and is it significant? How much time is required? These things might interest potential buyers more than the VRM configuration, for a product that is relying so much on its noise profile to justify its 20% price increase.

MSI confirmed in a livestream that the RTX 5090 SUPRIM uses a phase change material.

MSI also used a PCM/PTM on at least their high-end RTX 40 cards, you can tell by the thin crusty layer and spread pattern from TPUs images of both the RTX 4090/5090 SUPRIM that a PCM/PTM is being used.

I've had my RTX 4090 SUPRIM since launch and there's been no degradation in thermal performance, including on the hotspot.

 

[Dawora]

Yes, but will it have coil-whine?

it depends u PSU+GPU combo..
also every GPU is Unique

Just an FYI, this is someone who knows what they're doing and is servicing a ball bearing fan with a bit of oil.

Noctua is not the end-all-be-all-of fan information and opinions.

That's great to hear. Based on the images in the TPU review does it look like their new Vanguard 5080 is using PCM/PTM as well?

Yes, this looks like a PCM/PTM.

Given how MSI was one of the first AIBs to start using phase change/transition materials, it's safe to assume, unless stated otherwise, that all MSI's designs should be using them.
