New thermal paste?

I have recently moved from Hawaii to Arizona. Don't ask why.

I had my sig rig OC'd at 4.5 GHz, and was running average temperatures of about 60c when playing SW:TOR. After about two months of sitting at my sister's house unused and in the case box, I set it up last night. After about thirty minutes, it shut down, so I went into bios ant the cpu temp was at 95c and the core temps were over 100c. So I set it at stock, and shut it off overnight. This morning I turned it on and was checking it out and at stock it is 55c idle and running between 60-75c with workload. I an using Core Temp for reads in Windows and the bios says the same thing. Ambient temp in room is around 85f (that's about the same as it was in Hawaii, but it's a lot drier here) and thermal paste is Arctic Silver.

So my questions are:
Is this normal?
Should I just reapply same thermal paste?
Should I use a different thermal paste?
Or is there someone from AZ that could give me some tips?

Thanks in advance, and aloha.

I don't know why the past would have gone bad. Nonetheless, reseating the hsf can't hurt. Are you sure the fans are working. Dust? Yes, there have been people who have been baffled by their high temperatures only to discover a blanket of dust over the heatsink.
 
There it's no dust. That was one of my first thoughts, but I keep the case pretty dust free. I have to pick up some more thermal paste, then I will try that. I guess my thought was that it was sitting unused in the desert and maybe the paste dried? But alas, I will only be able to tell after I reapply the thermal paste anyways.
Thanks for the reply.
 
I've never heard of the h100 clogging though I seen some people claim that the liquid in those things separates after a few years, but I haven't seen that substantiated. If the pump wasn't working you would be getting rapid overheating, not just high temperatures.

You said you reset things to stock, is the mb doing anything crazy with the cpu voltage?
 
In hot environments, you must cut back. Let's say you set up at 25°C and you run at 70°C.
If the room gets up to 38°C (highly possible in AZ without A/C), your CPU will be 83°C. You can't cool stuff down by using hot air. A fan makes YOU feel cool because you sweat. Your computer doesn't. If you blow preheated 50°C air into the CPU radiator, you'll be at 95°C. Even if it doesn't crash, it will reduce the life of the CPU.

Fans in the case must move the air in one direction, and not fight each other. Duct to force air direction can make a huge difference.

The CPU fans should never have pre-heated air fed to them. ie - don't block the cpu fans with drives.

Hot air rises naturally. Cases with top fans, and CPU fans that face upwards are a big help. Why? Because the rest of the mobo has hot air rising from it, and it can feed warm air into the CPU fan.

A side fan that blows in with a duct to the CPU fan which blows upward and a top case fans that drag the air out, is pretty effect in a tower.
 
Sucker... At least you shouldn't have too much complaint about humidity here. :D

I would put money on the flight/shipping/however you moved it possibly jiggling things and breaking the paste seal. There's not much special here to cooling other than blowing your computer out every couple weeks and filter all your fans.
