Okay, so I'm sitting here with my Intel E7200 with an Artic Cooling Freezer 7 Pro at 43 - 45C. At stock speeds/voltages/everything. That's 30% load too. Why's my CPU running so hot now? lol

Ambient temps are probably +/- 5 degrees of the outside??? Idk, but I'll be sitting her sweating so, lol, not cool. When I had it down to 25C it probably was because I was in a 55F basment??? So you guys think it's cause of ambient temps?

IDK what your temps were before or what the ambient change is, but a air cooler is not going to cool as well in hotter temps.

I used to have terrible issues in my old house in the computer room even with watercooling my temps were really high and it was mainly due to the computer room being a spare bedroom upstairs that was always really hot. After moving the computer room to the basement I had no more issues. The computer is going to put out alot of heat and if the room is already toasty then it will be hotter then the other rooms. If you have a ceiling fan keep it running and keep the door to the room open to let some of the hot air circulate out of the room. unfortunatley there is not alot more you can do except move the comp to a cooler room if you want lower temps. Those temps aren't bad at all so I wouldn't worry to much. If the AC is on in the house and the room is upstairs and still hot then maybe shutting some vents in the basement (if you have one) would help cool the upstairs more.

I switched around the fan configuration and now the wall behind the PC isn't like 90 degrees, lol. Hopefully that helps. Other than that I guess I'll have to wait for winter when I can keep the room at 50F, xD.

There is a lot of talk going around about overheating laptop parts especially CPUs. Although in desktops they are talking about water cooling systems and I am not sure if they are going to turn there desktops into water coolers or what but with desktops there are many options available. Laptops are a problem. It's fine to have premium CPUs inside but overheating has become a major problem. Everyone wants fast CPUs and for sure nobody is ready to compromise on that and you can't make any changes on your own and mess around with a costly machine as laptop repair is also not a cheap option anyway.

That might be warm sure... but once it starts hitting 60-65C full load start really worrying about it.  I personally when I had my E8400 I tried to keep it at or around 50C winter 55C summer.

Might be from dust in the system, really warm room temps.  And having a 25C room temp is quiet warm so expect the CPU to be warm even under light load, but 43-45C is nothing to be worried about by a long shot.  Stock cooler would probably have it in the mid 50's maybe even reaching 70C under full load.

My e8400 runs at 60C under load with a Xigmatek s1823... Ive tried reapplying thermal grease but Ive come to the conclusion that my chip must run hot... I heard that if its under 80C than its ok.

60C is typically all you really want to run Core 2 Duo's.  70C would be considered max.  80C is really high but I've seen people run that with there's.  80C limit people started saying is what to shoot to stay under for i7.

The thing you really have to remember is that with electronics and heat the increase is NOT Linear.

so, if your room gets 5 deg hotter, your cpu may increase more than that, I've seen a system where it runs fine up to 79F in the room, once the room hits 80F
the CPU would jump 6 deg F for that 1 deg jump and all hell would break loose.

Reason:

vicious cycle. as electronics get hotter, the become less efficient, causing more heat, making them less efficient.

Add to that that hot air is less dense and can carry away less heat.
