I was just watching a TV show online (480p) and had 2 tabs of Google chrome running when the fans when full blast for about 5 mins (Could hear them).
Is this normal (Check istat pro for info). Thanks in advance.

Did you install the latest SMC and system update?

Yup, and also the fans are going all crazy again! Just played frontline commando and istat pro shows the temps to be:

The SMC update was really only for the 15". Have you tried an SMC reset, which helps with thermal management?

How do i do that? and thanks for the quick replies! :)

----------

update the keyboard is toooo hot to touch now, using an external mouse and keyboard.

----------

Is something still taking 100% of the CPU in activity monitor?

Well....no

Search google for "SMC reset Apple support" and click on the Apple Support Communities article. That will give you direction.

Sounds like a Flash issue.

I've also heard of rMBP fan issues.

Could be both.
How do I check whether it is a flash issue, I have reset the SMC and the temperatures remain unchanged should I give the Mac sometime to cool down?

You can install Click to Flash on Safari as an Ad-on which will help with heat if it is a Flash issue.

If you're not already doing so, use iStat Pro (free) or iStat Menus ($16) to get accurate readings of your temps, fan speeds, etc., rather than relying on your sense of touch or sound. A forum member has posted a copy of iStat Pro that has been "tweaked" to enhance compatibility with Mountain Lion. You can download it here.

The Intel processors used in Macs are designed to automatically shut down to prevent damage if they truly overheat. CPU Tjmax = 105C (221F), GPU Tjmax = 100C (212F) on i3, i5, i7 processors. (Source: Intel)

Unless there is a rare defect in a Mac, most temps are well within the normal operating range, considering the workload being put on it. Websites with Flash content, games and other multimedia apps will put higher demand on the CPU/GPU, generating more heat. This is normal. If you're constantly putting high demands on your system, such as gaming or other multimedia tasks, expect temps to rise and fans to spin up accordingly. It's just your Mac doing its job to maintain temps within the normal range.

It is also quite normal for your Mac to become extremely hot to the touch during intensive operations. The aluminum body transfers heat more effectively than other materials used in computer casings, so you will feel the heat more. This doesn't indicate that it's overheating and will not harm the computer to be hot to the touch.

Your fans are always on when your Mac is on, spinning at a minimum of 2000 rpm (for MBPs) or 1800 rpm (for MBAs, MBs and minis). iMacs have 3 fans with minimum speeds in the 800-1200 range. They will spin faster as needed to keep temps at a safe level.

If your fans are spinning up without increased heat, try resetting the SMC.
(PRAM/NVRAM has nothing to do with these issues, so resetting it will not help.)

The intake and exhaust vents are in the back of the computer near the hinge on all Mac notebooks (except the new MBP with retina display, which has intake vents along the sides at the bottom). The iMac vent is a slot on the back near the top of the computer. Make sure the vents remain unblocked to allow your computer to perform at its best.

Then this is a hardware problem, take it to the Apple Store. No wonder the fans are spinning.

Alright just called the apple helpline and they scheduled an appointment for me tomorrow! Hope I don't lose this gorgeous screen (guessing it is a Samsung)
