Macbook Pro Warm on Bottom?

I have done the above but to be honest I haven't noticed any difference.

I have noticed that some websites are worse than others, Ebay is one of them - if i am browsing that site for any length of time the bottom of my macbook gets very warm. If I come of that site it cools down eventually. What is it about the Ebay site that would cause the MacBook to get so warm?

Web browsing can include running various embedded programs that can be CPU hogs. Run Activity Monitor in Utilities and seen how much it's taking. I think the most recent versions of Activity Monitor will even display the individual URL if you're running Safari. eBay apparently runs on JavaScript, and some report extremely high CPU usage.

warm may be normal but you may want to reset your SMC and compare the results

Shut down

Disconnect all external devices

Reset the System Management Controller (SMC)

repeat 2/3 times

Reset the nonvolatile random-access memory (NVRAM)

(OPTION+COMMAND+p+r at Startup)

repeat 2/3 times

Then use safeboot (SHIFT at Startup)

Then reboot normally with devices disconnected.

All laptops need to vent heat caused by system components which increase under demand so a bit of heat or a lot of heat is not out of the ordinary.

some websites or tasks may be more intensive than others due to content or just bad implementation of the site. Some issues can also be exacerbated by conflict by one or more processes that wont play nice together.

For futher analysis you may post an Etrecheck report. The link is http://www.etrecheck.com

If you go the Activity Monitor you can see if a particular function on the mac is taking a lot of CPU or GPU resource and attributing to this heat, otherwise as mentioned some laptops get hot to the point where "lap" should not be part of their name and the word "oven mitt" would be better suited.
