I've got the 2.7 GHz retina and am getting temps up to 90 deg C/ 195 F!
What are you running. I am running at 42*C
doing "work" with about 30 tabs open, matlab, streaming a movie on Amazon instant...really interested in a way to cool down the computer because I am worried about heat damage
Late 2008 15" MBP. 160°F web browsing (30+ tabs open), writing in Word, et cetera (daily use). Around 210°F when encoding movies, and last week a freak 230°F spike when gaming while it was attempting a backup. Needless to say I am replacing my thermal paste- I think I dinged around the heatsink last time I disassembled it, so it doesn't conduct heat as well. Paste arrived this morning so I'll see how it goes.
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), or 1200 for the newest MBAs. Older iMacs have 3 fans with minimum speeds in the 800-1200 range, while the newest iMacs have a single fan, spinning at a minimum of about 1400 rpm. 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.

I have a Late 2011 15'' MBP, and after thermal paste reapplication, it never goes over 83-87 celsius degrees under heavy load. No one can say if reapplication is necessary for the health of the MBP, I've done this because I like it less hot, but the main reason is because the fans spin less quickly so the battery lasts more time.For example, when I make a long Skype video call, fans spin around 3100-3500 rpm (before thermal reapplication was 3400-3800), but if I play F1 2012 for more than an hour the fans reach 5800-6200, with temps around 78-85 celsius degrees, but I think it is normal for laptop.
10 tabs, watching a show on netflix, two of the tabs are youtube, tweetdeck, itunes open
Pretty good temps. Mine is 40 C plus just not doing anything. It probably has to do with the fact that my room is hot. When at work my temps are much lower I think.
My rMBP sits in the 42c range, almost regardless of what I do.
Also bear in mind when comparing temperatures with other retina owners that the base 2.3/2.4 GHz retinas run maybe 4-5 degrees cooler than your 2.7. If you're idling around 40 C that sounds just about in line with other mid or high range retinas. 90C load is normal as well for your model. GGJstudio's mega-post pretty much says it all.
thanks for the info, this is a HOT computer, literally
Not just Macs, most laptop PCs are also crazy hot under full CPU load. They can go mid 90 degrees Celsius while some laptops with dGPU go over 100 °C while gaming. Luckily, modern CPUs starting from the Penryn architecture can handle these temperatures without a problem.
90C is ok if you are under a heavy load.
on the bus right now listening to youtube and charging my iPhone.
Currently at 40* but i also just turned it on
