Why is your server room at 17 anyway? That is far, far below recommended temperatures.
And if you're dealing with high humidity as it is, this will only amplify the condensation problem by keeping the temperature lower...
Yup, I'd look at raising that at least to 25.
the problem is the high temperature we have in qatar, usually 46 - 38 C, so if i raise the temperature, i risk to kill the servers
That's NOT how air conditioning works. The temperature outside has nothing to do with the temperature inside. If you set it to 17, it is 17 no matter what the temp is outside. If you set it to 25, it is the same 25 as for any of us. Your 25 is not hotter than ours. What DOES matter is that the cost of cooling from 46 to 17 is much, much higher than cooling from 25 to 17. So the price for going unnecessarily low is more for you.

Intel and IBM tests in similar weather conditions (New Mexico instead of Qatar) years ago put optimum efficiency of the datacenter closer to 30-32.
Wow, that's 86-90F. That seems very warm!
We studied that project in grad school. It was pretty cool how they set it up. As long as humidity didn't get too high you could have ambient temperatures of ~100F before things started to fail.
We've done these tests (nonvoluntarily) with HP servers and they ran happily towards 160F!! But I would not recommend it since humans can't go in the room to replace parts.

I guess that makes sense. I mean, as a mostly-human being, Syracuse during the summer is often infinitely harder to handle than Dallas ever was due to how humidity affects perception of temperature. I guess it wouldn't be THAT different to electronics.
Although it is opposite, for electronics which are air cooled, high humidity increases cooling potential. For humans which are evaporation cooled, humidity decreases cooling potential.

IBM has shown that running at 37C consistently is far better for your gear than bouncing around between 15C and 20C.
-
Moving to SSDs actually makes it:
- Easier to cool as there is less heat generated and less power drawn.
- Temps can be higher than before.
- Fluctuations are not as big of a risk.
You can potentially save a lot of money with SSD for various reasons.

Fair enough...still, water on a board due to condensation is a risk.

Oh yes, you can't let there be water, ever.

i go to the server room to raise the tempreture, i realize that the remote controller is missing

Look in the couch. It is always in the couch.

You know it is an enterprise HVAC system when you have a remote

lol, it is not the TV remote controller, i'm talking about the AC

i know, and he know that i was joking

I live in the third world too, all remote controlled AC here, too. In the US, that's unheard of (at least to me.)

You're dealing with two Aspies...we tend to take stuff literally...

Most other countries make more use of using Mini-split HVAC units. Here in the US Central HVAC is more common even if it uses more energy (and you have to heat/cool everything instead of just certain rooms like you can with mini-splits, and no duct to lose the temperature in a mini split)
-
You can get more standard vent looking mini-splits but they aren't as common

Yup. It actually works amazingly well down here where the heat never stops.
