There are two alloy pipes that go into the head, 1 at the front and one at the back these tend to corrode over time and develop pinholes in them.

They are easy to get to if you take the intake manifold off, but they are interference fit and you can't get them out without destroying them. And they are like rocking horse s**t to get hold of. I had to machine mine up from some steel tube. You may be able to patch it with some steel seal putty for a temp fix but make sure there are no bits that can become loose and float around.

the pipe I got was 24mm o/d 5mm wall thickness. The size of the hole in the head was 19.07mm in mine, so I turned the pipe to 19.20mm x 40mm at one end and the other end was turned to 21mm with a flare on the end to stop the rubber pipe coming off. This is for the rear pipe. Hth
Is it showing hot? Was the newspaper rolled up, (sorry forgot to mention)
If you leave it you should hear the sound diff when the fan kicks in, Its an acquired sound
.Sounds like you might be in deeper and need to sort the leaks first.

The fan should change tune when it locks, and it starts to roar for want of a better word!
Also at 105c the Aircon fans should kick in to aid cooling, the 2 alloy pipes at the back of the motor would be the first port of call.

Sort the leaks out first and make sure system is filled and bled properly when refilling
