I am wondering that adding exhaust fan makes any difference on top of the current setup? Please advise.

You're wondering if venting heated air will make the place cooler..?

Yes, technically I want to know it really helps cooling the room.

Adding more exhaust capacity to get that hot air out is very important. 90F is not too hot for the hardware to be safe running 24/7 as long as you can exhaust that hot air out of there and keep the GPU temperatures safe. How hot are your GPUs running when it's 90 F in the room?

They are about 75-78F when it is 90F. Temps are here : https://ibb.co/kuBbAw

AC is a waste of electricity unless you have free power, your exhuast fans need to be ABOVE your rigs not in at the same level and you also need to make sure your room is somewhat presurerized

you can tell this by when you open the doors you feel the suction of the exhaust fans pulling heat up.

I have 30 rigs in my garage with only 1 of six exhasut fans going and my temps are like 30 degreees in winter, fall with three fans going like 60

How big size is the exhaust fans? I wonder what type is the most useful for venting.

Option 1 : http://www.globalindustrial.com/p/hvac/exhaust-fans/exhaust-and-supply/24in-heavy-duty-exhaust-fan-with-integrated-shutter-if24-4100-cfm?infoParam.campaignId=T9F&gclid=EAIaIQobChMIicG6v5K01wIVhoWzCh2UqwtCEAYYBCABEgIMOvD_BwE

Option 2 : http://www.globalindustrial.com/p/hvac/fans/blower/portable-ventilation-fan-12-inch-with-32-feet-flexible-ducting?infoParam.campaignId=T9F&gclid=EAIaIQobChMIicG6v5K01wIVhoWzCh2UqwtCEAYYAiABEgI5kvD_BwE

I want to test Option 2 to vent the heated air to see if it works better.

@Phil : Sorry to dive into your conversation.

If you have your GPUs only running the fans at 30-40% or so and your temps are still only in the 70s Celsius (going by the image you linked) then you really are doing great. If you would run your fans at 60-65% you would have lower GPU temps and still have plenty of longevity for the fans themselves.

I think the only thing you really need to be worrying about is ditching that AC unit and getting some good industrial exhaust fans installed... that will save you allot each month on your electric bill and keep things just as cool and probably cooler.

Thanks for your suggestion. I will buy a portable version to test venting the air.
