Your fans are loud because you are at 99%. In task manager it shows a 2% cpu usage, but in perfmon 99%. It also shows a HD read/write storm. Do you have a pagefile? What apps are you running that would require that much HD activity?

Frequency at 99% Ken, not usage.

Almost looks like whatever power options required for lowering CPU speed are disabled or the minimal usage being shown is just enough to stop the CPU from slowing down. I'd start with checking the power plan settings,

Power Plan - Select

which even if set correctly could possibly be affected by Toshiba's own power saving application (TPwrMain.exe).

Your Task Manager snips are not very telling as long as you do not show "Peocesses for all users" - the button on the bottom left. And then click on the CPU button until the most used processes are shown on top.
And for the Resource Monitor you should show the page from the CPU button - also prioritized by CPU usage.

You just answered your own question as to why the CPU is running at full speed all the time. This is the default CPU power settings under high performance,

The CPU will never throttle down when at idle. If you don't want it to run full speed all the time (not great if you're running it on the battery) then either set it to Balanced or set the minimum processor state lower than 100%.

What you need to check are cpu/gpu/hdd temperatures and fan speed settings. Obviously, the fan is getting cranked up because the cpu is running full throttle all the time and it needs to control temps. Fan speeds can be adjusted (depending on the mobo) in the bios or via 3rd party apps like Speedfan, there are OEM specific power management tools too for this purpose. Temperatures can be checked with speedfan or other apps like realtemp etc.

You can also create custom power plans and adjust that max processor state to your liking. Also, use balanced or power saver for non-cpu intensive tasks and shift to high performance when you need the juice.
