Mac Pro 4,1 is it normal?

It's quite normal. Your Mac is not overheating. The Intel processors used in Macs are designed to automatically shut down to prevent damage if they truly overheat. CPU Tjmax = 105C, GPU Tjmax = 100C on i3, i5, i7 processors. (Source: Intel) If you're not already using it, iStat Pro will give you accurate readings of your temps and fan speeds, among other things.
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). iMacs have 3 fans with minimum speeds in the 800-1200 range. They will spin faster as needed to keep temps at a safe level. If they're 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. 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.

For Flash-related issues:
- Find your Flash version and make sure it's the latest version available.
- Install ClickToFlash (Safari), Flashblock (Firefox) or FlashBlock (Chrome) to control which Flash content plays on websites.
- Use the YouTube HTML5 Video Player to watch YouTube videos, when available. (May impact fullscreen viewing. See link for details.)
That's only 13C warmer than your body. Relax.
I noticed that the ambient air is 36C. You will always have CPU core temp warmer than ambient air in an air cooled system.

What is the temperature in the room? If it is truly 36C then the room is a bit too hot. "Operating temperature: 50° to 95° F (10° to 35° C)"
If the room is not that hot, you need to improve the circulation around the Mac Pro. Even then, 90c under load is not a big deal.
My room is around 25-28C.
I'm looking to put new arctic silver on cpu.
So many thank for u to response my threads. Thanks!!
Read my earlier post. It is quite normal to reach temps of 90+C under load. Relax. Your Mac will manage temps and fan speeds to keep temps in a safe operating range. If it ever truly overheats, it would automatically shut down to prevent damage, as I said earlier. There are hundreds of threads like this. It's perfectly normal, even though you might not be used to it.
