I had a problem with materials melting in solidworks simulation, so I opened the "CPU cooler" simulation tutorial and took out the CPU used in the tutorial and put in a simple block added the same volume heat loasd spec, and surface goal , but the temperature ended up still  hitting around 3000 degrees c, so I am not sure whats going on, and why the temps are so high. Nothing else changed in the simulation except for that part. When I ran the simulation tutorial without changing anything it was at 120 degrees..its the blue colored square that I changed, thats all. Help
