Enough space between GPUs??

DAVIDLAROCK
 Share

Hi all,

 

I'm looking to get two 2080 TI cards on this mother board - https://www.asus.com/uk/Motherboards/ROG-MAXIMUS-XI-HERO/

 

Done some reading and if I get a card that's around 40mm thick, there will be a 20mm gap between the two cards.

 download.axd?file=0;2489285

 

My question is, would this be enough space for air flow whilst having two triple fan cards? I'm looking at the gigabyte windforce OC because those are the only 2080 tis I can find which are around 40mm thick.

 

Alternatively, is it better to go with blower style?

 

Thanks!!

It's not ideal. The upper card will be cooking, expect temps even 15c higher than the lower card. Blower cards (dunno if there are any for the RTX but I think so) would be better, or a combo of one card with blower + the other with normal fans (though that presents its own challenges - aesthetics and you need to keep in mind that the cards need to be of the same height because NVLink is rigid).

 

Anyway, best way would be to try blower, put them on water or just find a motherboard with 80mm spacing between the PCIE x16/x8 slots.

I see, there's an ASUS blower card I've seen but reading around people are saying not to go with blower style.

 

Are there any other problems with having a blower and triple fan? I don't care about aesthetics and NVLink, it's a gpu rendering machine rather than gaming.

 

I'm limited with motherboard options, as this will be prebuilt from a website and I'll just be slotting in the cards.

Yes because they are generally inferior to a triple fan solution - worse cooling and more noise. But that's all in single GPU department. Once you go with dual GPU you need to follow the advice reserved for small factor builds (ie. builds where the GPU airflow is constricted) and in those cases it's always recommended to go with blower.

 

As for the mixed GPU, if you don't care about aesthetics and NVLink then you just slap the triple fan on the bottom where it has presumably more air to pull, the blower will be the upper one because it doesn't care about the narrow gap and you're done.

Gonna be hot. Regardless of the version of card. Could put a fan on the side of you aren’t concerned with looks. 

 

Mate you gonna be in a situation to where you will be using both simultaneously?

Oh yeah, this. Ideally a case like the ol'n'good Coolermaster HAF 912 Plus :D

Right okay, thanks. I've found this motherboard as I'm going with the i9 9900k - https://www.asus.com/uk/Commercial-Servers-Workstations/WS-Z390-PRO/

It's the only board I can find which looks like there's a bit more spacing. Would this be a better option for two triple fan cards? I can ask the company to see if they have this board.

Could I request fans from the company? I'm getting it prebuilt, no idea how to put em in ha! 

It'll be for GPU rendering in redshift, that uses both cards.

I've already purchased the corsair 750d airflow and sent it to the company. It's the windowed side one. Can they add a fan there?

So you wouldn’t need a bridge for that right? Couldn’t you lower the second card on the board?

Like @Mick Naughty said, it's gonna be hot regardless but if you put more space between cards then at least you have a chance to balance it out. So yea, it will help but hard to say how much.

 

As for the case, the side panel is acrylic but honestly IDK whether that is feasible without changing it for something else. I mean, changing the side panel for a new one that has space for a side fan of your choice isn't a problem but that would need to be done by a modding company. If you are getting a pre-built it's hard to say whether they even do stuff like that.

Maximus VII Hero has only one slot lower than that and it's a 2.0 x4 slot :(

 

EDIT: OK, he wrote Maximus XI Hero but included a picture of Maximus VII Hero, hence the confusion. On Maximus XI you can lower the card without problems.

That board would be better for that. And no can’t really ask for that kinda fan placement as there isn’t a layout for it. Some companies make a bracket that could hold a fan but prolly best to just get fancy open air coolers. Put quality fans in the case and hope for the best.

Yeah this is the board - https://www.asus.com/uk/Motherboards/ROG-MAXIMUS-XI-HERO-WI-FI/

Could I put one card in that last long slot at the bottom and one in the top one?

I can ask if they have that board. I was told by the company that the fans that come with the corsair 750d are good so I wouldn't need to replace them. Is this true?

If not, what fans would be good to purchase? Dark base pro fans 140mm? I can see if they'll put em in for me.

 

Thanks both!!

If it’s a Corsair case, the fans aren’t good. Not for a pair of cards dumping that kinda heat.

Ah. Any suggestions for better fans?

My opinion since money expenditure is already in crazytown, this will eliminate cooling concerns and give you great performance.

I only run noctuas myself. Anything with better flow than what comes in a stock case would be better. I’m not sure what the conpany offers and why they wouldn’t wonna up sale anything.

I'm pretty new to configuring PCs, so I have no idea what that is ha! And definitely wouldn't have a clue how to install it.

Gotcha. They have 120 coolmaster fan master fans and 120 LL corsair. I'm looking at the 140 silent wings 3. I'll see if they can put em in for me.
