iMac temperature climbing too fast.

Hello, I'm extremely worried because the temperature on my iMac has been increasing too fast and to degrees I had not seen it climb before, it usually is at 89ºF to 92.5ishºF

But recently it has been climbing up to 95º when only watching a video in one tab and having Facebook (idle) in another. I mostly use it for that recently, although I've been playing some vanilla Minecraft and some browser-based games.

I'm using Macs Fan Control and that's what tells me the temperature (although I also have smcFanControl installed, but it doesn't run on startup, I couldn't figure out how to use that one well enough.)

I'm using a 21.5-inch, Mid 2011 with OS X Yosemite.

There is a little bit of background on this thread if that helps.

Editing to add:

• I thought perhaps one of the fans had stopped working, but the fan control program shows all three of them are.
• Before it was only the top left corner (facing the screen) that would feel hot, it doesn't feel particularly hot lately but behind the apple and on the other side of the back feels a bit warm.)

Thank you.

95°F would barely be considered warm. If it is approaching 95°C, then it would be time to do something.

But it never gets this hot And I've been monitoring it every single day since I installed the fan control, what could be causing this? Right now it's almost at 94º and I only have a browser open.

That model iMac is one of the coolest-running models Apple ever built, and 95°F is no reason for concern. It's barely even warm. 

Attempting to circumvent the iMac's cooling system is ill-advised for a number of reasons. If you are using non-Apple software to do that, uninstall those products according to their respective instructions.

Over time, there may be an accumulation of dust within the iMac's enclosure that should only be removed by an authorized Apple repair facility. Arbitrarily increasing exhaust fan speeds will only accelerate the need to do that, or decrease the affected hardware's lifespan, or both.

I'm using that program because the local Authorized Service Provider didn't plug the fans to the HD when I had to replace it back in May. That's why I linked the other thread to my question.
It was before May, I don't remember the exact date, but it got serviced then, after that the fans were running at full speed all the time.
Since I installed the program months ago, until now, I had never seen it get this hot even when using much heavier programs or using it for much longer time periods. I don't know which temperatures are safe. There was no way to give feedback to Apple about their new ASP.

That changes things considerably. The iMac's thermal sensors are absolutely, positively required for proper operation. I cannot emphasize enough just how bad an idea it is to bypass them. There is no software substitute for operable hardware.

Fix your Mac the right way. Any Apple Authorized Service Provider would know how to do that. To find one, start here: Genius Bar Reservation and Apple Support Options - Apple. Scroll to the bottom and click the blue Get hardware help button.

Good luck.

They are who messed it up in the first place!

They messed it up; they can fix it.

You should not tolerate incompetence. Make it their problem. An iMac's hard disk and its related components are simple "remove and replace" items.

I really hope you're right, I've been having trouble contacting them online. It's extremely difficult for me to take it to service and it's the only "machine" we have in the house :s (no T.V. Radio, or whatever else people use, and no other way to get online either) I need it to shop for groceries which get delivered, to pay (all) my bills online, etc.

I understand. They clearly performed a disservice by improperly repairing your Mac.

Your choices amount to taking it back to them for a proper repair, or finding another AASP to to that, and probably paying for it all over again. If you do nothing, that little problem will eventually become a bigger one.
