CPU getting really hot

My CPU's temperate is quite high. While playing the new Battlefield Hardline Beta(High graphics) my CPU can easily exceed 65 C, and has gone up to 70 C before, which seems way to hot. Right now to try and fix that a little, I have a fan plugged into the wall sitting behind me, blowing towards to the computer(And me), which helps a little. I did have to send my motherboard back to ASUS a little while back because one of the audio connectors fried, and in doing that, I had to take the CPU and heatsink off, which may have messed up the thermal pastey stuff, im not too sure. I'm considering buying liquid cooling, but I dont like the idea of liquids near a thousand dollar computer I can't pay to have replaced anytime soon.(Im also 15 and have absouletly no money at all)

Well, there's your problem chum'. You must reapply the TIM if you reseat the heatsink, you must also clean off the old stuff.
To do this, you'll need to buy in a tube of thermal paste and a bottle of isopropyl alcohol, clean off the old paste and add some of the new, then remount the heatsink.

There are many thermal compounds to choose from, as much as a few people may disagree there really isn't much in it in regards to temp difference (There is a lot compared to the stock goop), and especially not with the stock cooler.
You can look up some tutorials if you get stuck with any of this.

It's a strange...
If this is an Intel CPU, that's not too hot.

If this is an AMD CPU, you're too hot but still below the thermal throttling limit.

If you are not overclocking, something like a Cooler Master Hyper 212 EVO would be a great budget heatsink for either AMD or Intel.

*OR* You could just get some new high-quality thermal paste (Arctic Silver 5, Arctic MX-4, Noctua NT-H1) and a cleaning kit like ArctiClean. Clean the old paste and apply new paste.

It's a strange thing, but to clean off the old goop I like to use ear-cleaning buds - I'm serious xD You have no idea how well these things work compared to the conventional methods. It's a lengthy process to do it right, especially because the stock stuff is pretty solid and flaky, but just get the majority of the goop off using something like plain bogroll and then attack it with the ear tips, sometimes dunking them in the alcohol and sometimes not.
Repeat until it comes back clean (Like wiping your ass, similar method, different coloured squidgy stuff).

Probably going to get a lot of flack for it since they're cotton and therefore pretty 'lint-ey'. I make one final sweep with a lint-free coffee filter, but it's usually not that necessary if you don't want to fork out for a pack of those.

Well theres a slight problem, Im 15 and cant get any thermal paste stuff. My dad is going on a camping trip for 2 weeks, and i doubt my mom will buy it for me, and right now the computer is idleing (with this one tab open in chrome) at 46 C.

Not to worry, fortunately you're within safe temps for that CPU, at idle anyway.
Certainly not great temps, but the limit for an AMD chip is around the 60-70 mark, until you can find some thermal compound I would recommend continuing your current procedure of fan pointing at it, and lay off the gaming a bit.

Certainly don't run any stress tests, gaming thankfully isn't going to rocket your temps too far, usually only about 10-20 degree's over idle, running a stress test like Prime95 will probably turn that into +40, putting you well over the Tj max limit and potentially damaging the CPU itself.

TIM is very cheap, as is the alcohol, for the sake of longevity I would recommend you keep things as cold as possible until you can find some, make it a priority. Perhaps look in to ordering online? (Amazon?).

Thanks for the best solution by the way!

I have looked into Amazon and Newegg but I need a credit card and thats the big issue. Oh well, I will just have to keep an eye on it, not let it get too hot. Thanks for the answer!
