Anyone have any suggestions on a good cooler? When using Handbreak and a few other programs here lately my temps have hit close to 100c. Price is not really an option, just looking for a good solid cooler.
Complete waste of money
Thing is the MBP's don't pull in air from beneath like most windows laptops. So the "cold" air the cooler blows at the bottom doesn't really have any effect. Most windows laptops have a grill of some sort on the underside where the fan pulls in air from. In that case the coolers help a lot because it blows cold air to the fans which significantly helps to transport heat away from the heatsinks. I have a cooler stand thing with integrated USB hub and SATA connector and it has never, not even by 1 degree, cooled my MBP. The bottom case maybe by tiny amounts but that doesn't change internal temperature. If you find a cooler that get cold air to the fan inlets at the back, then it would help.
You wont be able to make your CPU run any cooler, thats just the thermal constraints of the MBP. The bottom case etc is only at 35-40 degrees.
What can help though is to lift the back of the MBP up allowing for more air to be able to sucked in.
I experimented on how to get my MBP to run cooler and at one point I took the bottom case off, placed the MBP onto to three 3cm thick styrofoam bits (on big one under the battery and SSD, one under the Optical drive and under the top right corner) this allowed for the fans to get much more fresh air and it no longer insulates. CPU temperature dropped from 85-95°C to around 72-75°C. Massive difference!!! Sadly you cant use your MBP like that. So not really an option but quite interesting to know how much cooler the MBP could be running with better air intakes.
I have been using a Peas Cold Therapy - Medium, I picked up from CVS when I had a black eye. When watching heavy video, it cools my 2011 MBA down for well over an hour.The bottom of the MBA and MBP is a heat sink, but blowing cool air on that won't have much effect on the inside temps. You might be better off turning the cooler upside down to cool your lap if the machine gets uncomfortably warm.
Price is not really an option.
Even if it's just for peace of mind, or to keep your lap cool I don't think it hurts to have a fan. I know my 2009 MBP runs cooler for me than for my kids who do a lot of videos, so I've tried various fans.Anyone have any suggestions on a good cooler?

just use SMC fan control and set the fan speed to max...
along with using a small book and rest the bottom rear side of your laptop on its edge so air can flow underneath it.
Wont stop the CPU from reaching 80-100°C. Not in my experience, over six different mac notebook models at least, when the CPU is maxed out.
The extra airflow makes minimal differences.
Yes i know, completely correct. What I meant by saying that was that it also will nearly not at all make a difference.What I meant was in support of not buying any cooler as they are not effective and not worth any money.
It won't really bring CPU temps down, but if you get one it'll probably make the computer more comfortable to touch/use.
That's why I have one - makes the laptop cooler to touch and it also raises the laptop a little bit on my desk. But CPU temps are the same.
is it OK to boot up my macbook with my laptop cooler plugged on to it? will this be a problem?
i've also noticed a very low humming noise (audible only at night) when i sorta get near the notebook... does anyone have this problem,,, i have a macbook 2011 core2duo...
Heres something. Like the thing I did with the styrofoam.
I removed the bottom case from mb MBP. Taped some folded together bubble rap (about 1.5cm thick) over the battery and CD drive, and propped the top left hand corner up with some plastic thing.
I was rendering a scene which completely maxes the CPU out. Again the temperature of the CPU was at 72°C and fans at 4900rpm. Very pleasant that it was this quiet.
When I then placed the MBP onto my cooler, which therefore blew coldish air at the logic board, the temperatures dropped by about 3 degrees. 68-70°C maximum.
Im going to buy a used bottom case on ebay and cut hundreds of tiny holes in it, stick wire mesh on the inside (so nothing gets through) and use that. I predict it make a big difference, because cold air will get pulled in and warm air can escape aswell. Lets see. Ill post when I have it done. It should end being cheaper then most "good" coolers.
