Ways to cool down MBP?

I have a 5 1/2 month old MBP (13") & it gets hot (as do most MacBooks from what I read). I have a cooler (a Targus) that I plug into my MBP with a USB & my laptop still seems to get hot (or really,really warm).
I read about that fan control app or whatever,but I don't really know how to use it & I'm that I'll get into settings that shouldn't be altered & screw up my computer.
My computer's CPU's temp is 8O right now (I'm unsure if its good,okay,or bad) & I hear the fans over the cooler's fans.

What are a few ways to cool my MBP down? & What are a few good coolers for laptops?
 
use the fan control app. it allows you to customize your own fan speed. it's a simple click of a button to change the speed.

default = normal fan speed
higher rpm = higher fan speed
customize = what you set it to be.

this is probably the most helpful since you're able to control the internal fan manually. no need for accessories.

Your temps are quite normal, as dozens of threads on this topic will show. The fans will automatically spin up faster when the temp goes high enough for a sustained period of time.
 
I put mine in the freezer for a couple of minutes, make sure not too long though, don't exceed 2 minutes or it might cause damage

:eek:

Wow, I just about feel off my chair when I read this. This is a very bad idea for many, many reasons.

Another poster mentioned condensation and moisture which is absolutely correct but that is not the biggest problem.

The rapid expansion/constriction of material is the most common failures in electronics. The computer heats up, parts expand gradually and then they cool down and constrict. This constant movement (though tiny) causes minute fractures that can cause all sort of problems in the long run. Intermittent issues, fractured traces, cracked chips, the list just goes on and on...

Forcing rapid cooling of expanded parts only exacerbates the problem; meaning you are shortening the life of your computer.

Remember that keeping something cool from the onset versus cooling down a hot object is a much more healthy approach for electronics.

When I play a game that I know will heat up my MPB I put the fans on pretty high (as much as 6200). Replacing a fan -if it ever did go out- is much simpler than trying to track down an intermittent short on a trace somewhere on the motherboard.

I have been playing DOA a lot here recently. I can keep my MBP very cool if I run SMC @ 6200 before I start playing rather than letting the fans try to cool a hot notebook.

Try it and see...


Cheers!

do the 13" MBP's run hot?

I'm in the market for one and I can't get a clear answer really. I have a Vaio that feels like its shooting flames out from underneath when its on my lap for more than 10 minutes. I was hoping to avoid that.

I've gotten my new 13 inch up to 80C during some DVD encoding. Any strenuous activity will bring the CPU up to the 60C range and thats when the bottom of the laptop and the top edge above the F keys starts getting very warm to the touch. At that point it can get uncomfortable to hold it on your legs.
 
I just use smc fan control. I leave mine on at 6000 when I am without air conditioning. Florida summers are killers.

its a joke

How is it a joke? He says 'make sure you remove it after 2 minutes'. Sounds like he is serious to me.

Personally, I undervolt to help my temps. Although the MBP is safe generally up to 100c
