Well, only option 1 seems possible. When mounting the Scythe the manual was talking about 4 rings that weren't delivered with my motherboard so I mounted them without it. But I can't imagine that makes the difference. I have two exhaust fans blowing outside and the fan of the Mugen is also blowing outside.
Thermal paste, well, maybe. Applied 80% and smeared it out.
House temp: 25/26c.
Actually, I see a few in just how you describe it. One, the thermal paste. Sounds to me like the people posting here are right and you used WAY too much. I know for a fact, I used WAY too much as well, but I still get 40's to 60's, where you are getting much worse than that using the same cooler. Too much thermal compound and the cooler can't function properly. The longer you use the computer like this, the more likely the CPU will soon be ruined. You want to get some new thermal paste (TIM) and redo your CPU, ASAP.
DO NOT Overclock the processor like this, get it down to stock speeds until you can change everything.
I'd search on Google to find some videos showing how to remove the thermal compound.
Then find some videos showing how to install it correctly to achieve the best performance.
Remember, less, is more.
The other is your cooling fans. You want more fans blowing in than out. The idea is to create positive pressure of cooler air in the case so there is more cool air flowing over the surface area of the cooler before it heats up and exits from the case.
If you have 2x's as many fans constantly blowing hot internal air out, you're going to create negative pressure in the case and there won't be enough cool air coming in fast enough to go over the CPU cooler.
Think of it like a fish tank. With water constantly pouring in the top and a hole draining from the bottom. If the amount of water pouring from the top is greater than the water draining from the bottom, the fish will be fine and get a constant amount of new fresh water. But if the hole in the bottom is too big and the amount of water pouring in is too small, the tank will drain completely and fish will die.
You want to get a good balance of cool air coming in with just enough hot air coming out. So case design, the speed, direction and CFM of the fans you are using will all be factors in how efficient this process will be. You may have to experiment to get the best results.
