Number of Cooling Fans in 2.53 uMBP-SD?

[maestrocasa]

I just got one of the new unibody MBP's (4GB, 2.53GHz, SD)

Anyone know how many cooling fans this thing has? I have the iStatPro widget, and it shows the CPU temp at 88 C and only shows a Left Fan spinning at 5700RPM.

Shouldn't there be more than one fan? when will it come on?

there is only one.

even the 15 inch model only has one fan?

what's a good operating temp for the CPU? should I be worried when it gets up around 90 C?

The 13" MBP has one fan, where as the 15" MBP has two.

No, the low end Mid 09 15" has one fan. The "double heatsink" appears and disappears with the 9600M. (It has a second heatpipe too)

I think he meant the unibody MBP's.

yea the low-end 15" now has only a 9400m, same config as the 13" model, and thus one fan?

Seems hard to believe that it only needs one. I guess the lack of a discrete GPU means it's cooler? Seems odd that iStat would list "left fan" instead of just saying "fan." what about the CPU temp? Is 90 ok?

BTW, considering that the new 15" & 13" uMBPs are essentially identical, what's filling the extra space in the 15" case?

The components on the logic board on the low end 15" are much more spaced out compared to the 13". Other than that, the battery is bigger, and that is about it.

Just download the iStat Pro widget, it will report indirectly how many fans you have, i.e., by providing you the fan speed of one, or two fans.

That's what made me ask. iStat says "left fan"
But makes no mention of a right fan. Seems like if there was only one fan, iStat would just say "fan"

 

[iLog.Genius]

There is only one fan. Saying just "Fan" makes as much sense as just saying "Left Fan". It's just how the developer written the utility.
