Issue report: MainThrd cause overheating on X201
I just had my first run with the beta on my laptop as I am currently on the road and do no have my desktop available. I followed the first steps and introductions provided here.
My laptop is a Lenovo X201.

The issue: I started up the client I decided to install "And yet it moves" and "Steel Storm", which downloaded fine (did not try to start them). After that I decided to download TF2 (just for testing, I have no hopes that it will run on my lapop)

The "preparing files" screen came up and I left my laptop for a few minutes. When I returned I saw that the bar was full (maybe not to 100% but surely almost full).
The problem was that Steam was unresponsive to any input and my CPU temperature was up at 85 degrees celcius. I checked my system settings and saw that "MainThrd" was up and using 104% of my cpu. I closed my laptop at let it cool down.
After opening it again Steam was still running, the "preparing files" screen was gone by MainThr was still taking 104% of my cpu, so I killed the process. Steam closed acordingly.

After that I booted Steam again. It ran fine and now and is downloading TF2 fine with using about 24% of my cpu, which seems fine.
Sadly I do not know how to provide more information on this. I will download TF2, remove it afterwards and see if I can reproduce the issue.

I have the same experience on my T530. I start the TF2 download and MainThrd immediately jumps to ~100%. The "creating local game cache files" step takes abnormally long (several minutes), and then the download starts. The first time I tried it got to 37% downloaded before freezing, and MainThrd was at 100% the entire time. Quitting and then trying to resume the download didn't work, it hung at verifying the content, though I was able to cancel it successfully. I then deleted the local files, and when that didn't bring down the CPU usage I quit Steam.

I currently have it trying again, and it has shown the exact same symptoms so far (I started the download before starting this reply, and it just now finished creating the cache files). If the behavior changes at all I'll post another reply.

EDIT: The second time through it installed correctly, so it appears to be somewhat intermittent. The only new thing I noticed was that the CPU load would drop off entirely if the download stopped for whatever reason (shortly into the download the bandwidth went to zero, and I had to pause and resume the download to get it going again, during which time the CPU load was minimal).

There are a bunch of similar reports on here, so I figured I would link to all the ones I could quickly find.

steam for linux is just such an incredible power waster... my EEE 901 has 20% load even with no steam windows open or downloads going on.

try cpulimit. I found that I can chat with 5% maximum steam load allowed.
