Would a GPU disable itself if it does not detect a fan connected to it?

[raptorcruz]

There are very few Geforce 16-series cards that are available locally here in Japan.
However, all the cards that I find are know to be loud (Asus RUG, Zotac, MSI WIndforce)

I use Speedfan to control all the fans on my system. I want to control the GPU fans myself.

I looked up the cards (the ones that are are available here) on review sites and inspected the pictures of the card's circuit board. They all show that these cards have their own 3 or 4-pin connecter on the board itself for their fans.

So if I wanted to control the fans myself, could I disconnect that 3/4-pin connector from the GPU, splice it and make an adapter to plug into my motherboard, and then be able to control the GPU fans myself?
(I would control the fan speed based on the GPU sensor)

Or is there something in the GPU card itself that would disable the card if it doesn't detect a fan connected to the GPU's board itself?

That's all I'm trying to find out. A definite answer to the question of whether or not GPU's have some fail-safe that disables the card if no fan is detected on the GPU fan connector.

Does anyone know?
Thank you.

MSI Afterburner: custom fan curve.

Generally no, card does not disable itself without a fan.
Watercooled cards are a notable thing that does not use fan connector on the card.

I second to @birdie though that unless you want to actually change fans, using a software that allows controlling GPU fans - like MSI Afterburner - is the way to go.

No it wont be disabled. If it would get disabled all those gpus with waterblocks would be useless. (like fe cards with custom waterblock)

Thank you everyone.
Very good point. I don't know anything about water cooling, so I didn't think about that.

FYI, the cards available are MSI Ventus cards, Zotac Twin, and Asus RUG.
I don't have first-hand experience with MSI cards, but from what I've read, even with Afterburner, you can not lower the fan speed lower than 1500rpm on MSI Ventus cards. And I heard MSI's fans at 1500rpm are not quiet either.

The Asus ROG seems to be the only high tier GPU you've listed, the other 2 are the lowest tier GPUs in their own series. The lowest fan speed set in Afterburner should be actually very quiet to most of the users, unless you have abnormally high requirements.

 

[raptorcruz]

Sorry, I did type ROG, didn't I? No, it's not Asus ROG STRIX line. I meant Asus TUF. The Asus TUF line is not their top tier stuff. It's the line that everyone complains about their fans being so loud. lol

Thanks though. You guys have been very helpful!

Also just to clarify: MSI Afterburner can be used for almost any card, and not just MSI cards. It's one of the reasons it's recommended so often.

Yes, I understand that. Thank you!

By the way, if anyone is looking for a Geforce 16-series card and is serious about buying one, please let me know and I can look for one here locally.
I know they are very limited everywhere, but there are a very few that I've seen here locally here in Japan. I could look around if someone wants me to.
However, please keep in mind that pc parts in Japan are generally more expensive than the US.
The average price I find here for the 1660 Super are in the $350-$400 range. Those are not jacked up prices. It's just more expensive over here.
I bought my 1600 Super for $390.
Anyway, if anyone is interested, let me know and I can look around over here.
