|Intel stock fans that came with your CPU had a preapplied thermal compound so you should not have needed it (unless you 'cleaned' it off of the heat sink or put it down so dirt may have stuck to it and now is between the heat sink and the CPU). Your graphics card already had its heat sink attached at the factory, so you need not have to worry about that (unless you removed it).|
200F=93C, 231F=111C both are way too high and the machine would have shut down due to the heat probably before reaching 90C, certainly way before 111C. What are you using to measure your temps? Try your BIOS temps or Speedfan and see if you get the same readings. and post these back. If your temps are that high, you will need to investigate, it is possible you have one or more mistakes that are causing this. One possibility is that one or more of the push-pins that hold down your heat sink are not locked down properly and you do not have full contact between the CPU and the heat sink (note if the heat sink is loose, crooked, or all push pins are not fully down, or look from the back of the board to see the locked pins). In this case, removing the heat sink, cleaning off all remaining thermal compound from both surfaces (alcohol & and old credit card to help) and reapplying the correct amount and making sure it is locked down fully. Look, read:
Another possibility is that the fan(s) are not set up properly. You need to make sure that the CPU fan is plugged into the correct connector on your motherboard so the cpu fan speed can be adjusted by your motherboard. You need to make sure that your REAR fan is blowing OUT of the case to exhaust the heat out of the case. You should not have side fans. You MAY use an optional front fan (low in the front blowing INTO the case. And you need to make sure you have space for the air to flow between and around components without obstructions.
If the temps are not really high, you should know that a power supply that has too little available wattage, or too little available 12 volt amperage, CAN cause your system to freeze or crash when your graphics card is under full load, so you should replace the power supply with an appropriate one. Avoid the cheap ones, if you spent a little bit more last time, you would probably still be using it. Look for one with only one 12 volt rail and at least 80% efficiency rating.
You have to be a little bit crazy to keep you from going insane.
