case with bad air flow

[tuxedocat]

hi
i have a stock dell 660 with a stock intel cooler my i7 3770 idles around 45 degrees c and surfing the web it peaks around 62 degrees c ,but gaming it can peak at 84.

my case sucks it only has i think an 80mm exhaust fan and thats it with no room for more.
i tried opening up an empty optical bay and placing a fan near it but it did nothing for temps.
i would buy another case but i afraid i would never figure out the dells motherboard wiring.
i just paid 330 bucks for the cpu and dont want to see 80 degree temps.

would placing an aftermarket cooler like cryorig h7 in a case like this that has no air flow even help ?

Your processor is an older generation. When last have you opened that case and cleaned out the dust with canned (compressed) air? Most cases of older computers getting hotter is doe to dust build-up on the cooling components.

i cleaned it out about 2-3 days ago when i installed the i7 3770. when i was running the i5 3300 it was about 8-10 degrees cooler.i thought when i upgraded the cpu and applied arctic silver 5 that it would be at least a few degrees cooler.
i have already made sure the the heatsink is well seated.
i am just debating 1 of 3 things
1 buy a cryorig h7 and try that (i am doubtful seeing as theres no air flowin my case)
2 buy a new z77 mobo,case and cryorig h7
3 just build a decent z97 instead of dumping more money in an old z77 build

Test it by taking the side of the case off and direct an outside fan into it. If you get a drop in temps, then it's case airflow.
