My fans dont ramp up!

I was performing a test to see when my fan would ramp up in my new MacBook Pro. I fired up Safari and opened up as many youtube videos until the processor was clearly struggling to keep them all running. Maybe 10 tabs. Then in iStat, I watched the CPU temp and fan speed. My fans ALWAYs lug around at 2000 RPMs give or take a bit. The CPU climbed up until 90 degrees C and the fans were still unchanged. Is this normal? I stopped the test at 90 C fearing damage or a crash.

What is going on here?

Macbook Pro, 2.53 ghz, 15" antiglare screen, Mac OS X (10.6.1), 4 gigs RAM

I was not aware that it only has one fan I just assumed it had two since the left side was hot and the right side was not... But I bet that's just where the video card is or something like that... like I said since I took it in to the apple store it's been running cool ever since..

actually bartino my fan shut off all the way and wouldn't turn on so when I installed the fan control it told me it was running in the 100 degrees Celcius... range... But I took it to apple and they reset the fan and everything is fine now...

You might try updating to Snow Leopard 10.6.2 Many people are reporting cooler temps with this update.

You can do this by going to the Apple in upper left corner of your screen and using software update.

hope this helps.

Best,

I confirmed with Apple that the 13" MBP only has one fan. Also, the base line 15" MBP also only has one fan. The other 15" models have two fans.

I was concerned for my Nephew when he got the baseline 15" MBP an Istat Pro only showed one fan.

Best,
