E8500 overheating in the summer's heat

[alhanelem]

summer is here in australia and its already hitting 33C outside (93F)
so recently my e8500 has been reaching pretty high temps lately
idles at 40-45C (104-113F) and maxes at 75-80C (167-176F)

so i have two options:

quickly buy these at my local computer store:

http://www.dcomponline.com.au/productview.asp?proid=8486
http://www.dcomponline.com.au/productview.asp?proid=8487
which comes to $77

OR

order these online but have to wait a few days for delivery

http://www.pccasegear.com/index.php?main_page=product_info&cPath=207_23_845&products_id=16986
which comes to $94 PLUS $29 shipping fee = $123

P.S im only interested in getting something for my e8500 at these two sites NO WHERE ELSE.

noctua also makes great coolers, up to you on your budget

it seems the temps are better on the CoolerMaster Hyper 212 EVO than the kuhler 620 BUT wouldn't that be dependant on the room temperature?
wouldn't watercooling be better since the air temperature is kinda high?

 

[alhanelem]

any advice on the coolers from my local computer store?

i just took a look at the dimensions of the 212 EVO and its 16cm high
my case is only 18 cm wide, will it fit?
