First build/heating issues

[Majorllama]

Heres my current setup (nothing overclocked):

CPU: old i7 (920)

GPU: Stock GTX 770 

PSU: Corsair 750 w something a hoosit. 

MOBO: Asus rampage gene III

RAM: 12 GB of Vengeance 

HDD: Seagate 1tb 7200rpm 

Case: Some cheap shit I found for like 30 bucks (which I assume is part of my issue) 

 

I have two intakes, One from the top of the case and one from the side panel that pulls fresh air onto the GPU. The only exhaust is past the rad at the back of the case. 

 

Ok. So the Issue I currently have with my tower is heat and dust/fur. My house is all carpet and we have two cats. I knew hair and dust was going to be an issue right away so I went with watercooling on my cpu (h80i) and I tossed all the stock fans for some cougar ones I got a nice deal off newegg for. I also nabbed some filters from a big brand that I cant recall off the top of my head at the moment, but they rock. 

 

The room my computer is allowed to be in runs from mid 20's Celsius to 38C+ at times (at night when I do MOST of my heavy gaming it can actually cool off quite a bit to. I cant change rooms or use air conditioning and for external reasons I have no power over that at the moment. Anyway, with the room running temps like that Ive found my computer to idle at ~40-45 C on GPU and ~ 45-50 C on CPU. When I start to stress the system and play my games it can throw my GPU up to a max of 85 C and my CPU at 55 C. 

 

I clean out my rig twice a month and dedust all fans/filters. Its sorta required with the cats n stuff. But im worried that running those temps on a pretty regular basis (almost every day) will kill something. Im also wondering if I should flip my PSU over and pull in from the case since its not getting much of an intake from my carpet. Should I add a third intake or a second exhaust? I need help. I feel like its running way too hot. 

 

If you guys have any tips for tweeks in my build or just to tell me that im being too paranoid it would be a big help.

That's fine. You are A ok. you should have more pressure in the intake than the exhaust. Negative air pressure causes dust faster. 

Cats are a real trouble. the Hair makes a filter or sorts and is electrostaticly attracted to stuff. 

Try an air filter? 

I suggest getting a like 20 inch furnace intake filter (bout 1-3$) and strap it on the back of a box fan. The blue ones, no the really fine ones. Replace it every week or so. 

This one would do better for dust and allergens but costs more-

Those temps are perfectly fine. The GPU is set to work at 85ºC and the CPU can get up to at least 70ºC before facing even a minor problem.

I just plain dont have the room for something like that. I would like to get it off the floor and on the desk, but  I lack room.

your temps are fine, as for dust..
coming from someone who has OCD best bet is to make sure your case as enough volume in it for your pc to breathe and/or has enough fans to get air in and out, it doesnt need to be a ton of air though.
"posative pressure is better" only works with filtered intakes (and you need 2 filtered intakes for every exhaust otherwise its still going to be a vacuum).
if you have a pc with 1 intake and 1 exhaust youll bring in a ton of dust anyway.
2 intakes 1 exhaust you'll bring in even more dust.
2 filtered intakes 1 exhaust, 0 pressure very low dust but can be noisy because you need high speed high pressure fans to get any airflow through the filters.
i have yet to see dust and cat hair manage to get through side panel gaps that it could get through an unfiltered fan anyway.
dont bother with any ghetto mods, just get 1 or 2 120mm filters and put them on the intakes, cant afford that? keep cleaning...
the finer the filter the less your pc will get clogged but itll also be more restricitve and your case temps will rise..
I dont even run filters personally, by the time theres enough dust to make my cpu/gpu temps go up 1-2*c its generally pretty thick and takes about 2 months, in which time i unplug it all and get a pastry brush to brush off parts and an airline or just blow it out manually, its not hard.
keep your pc off the floor aswell, keep it high on a flat surface making sure the cats aren't on it or get them out of the room completely, theres no reason for them to be in there anyway, they serve o purpose, heck turn them into brushes (totally joking).
pc components are made in clean rooms for a reason.

No where in your house? I mean you can even put it near a wall or in the corner. Also worth noting make sure you are replacing your furnace filters at least once a month in your air intake. A lot of people forget. I have a dog and it makes such a difference with dust and hair.

keep your pc off the floor and keep the dust filters in, when you dont have much dust removing the dust filters can be good but in your case, keep them in.  

 

In the way of your temps, they are fine, my 4670k runs at 55c during gaming on its overclock (4.2GHZ, 1.2V) even that is perfectly fine.  I would say once you reach 75-80 cpu temps thats a problem.  85c is quite hot for a gpu, but if it doesn't go anything above that, I guess its okay.

Oh they are reusable filters. I just take em out and clean em twice a month. Thats it. And I would love to get it off the carpet, but I just plain lack the space.

grab a plank of wood or a mat or something and put it underneath it at least
