Hello,

While I am gaming, my screen keeps freezing. I read online that the cause is due to something over heating and my graphics card goes to 45 C but my CPU is at like 65-72 C. I use the stock cooler with my fx-8350, I think that it is most likely the cause. I think I should buy a new fan & heat sink, but which one should I get? Also, do I need thermal paste? How do I remove the old stuff that came with cpu? My current stock cooler is a little noisy, so anything quiet would be nice.

I also only have a budget of $40

I only like to buy from newegg.

I have 360mm/240mm/140mm rad, cooling my 8350 and sli 770's. My idle around 24c, and rendering temps (vary upon which oc profile I load) stock are usually 54c, water temps 30c. 4.8 ghz rendering temps 62c, 5.2 ghz rendering 70+ which is to hot. I think chip design is 65-70c tops. I know shut down temps where the computer shuts down to protect itself is at 75c.

Id suggest the hyper evo as stated above. Its definitely enough for stock, and should also handle a decent overclock as well. Anything 4.5-4.6ghz and I would suggest a bigger air or watercooler for though.Anything higher than 4.8 and your going ot need massive air with best in class case cooling, or true custom water like mine.

Sorry dude, I have to disagree. Are you a sales guy for Corsair or something?

Low 70's for CPU (or GPU) temps are good - if under load. Though I would be concerned if the CPU is idling at 65-70C.

Personally I believe that water cooling has its place, as does phase change cooling (small fridge like case or liquid nitrogen poured onto the part) - but all these methods are not necessary for the average person or even most enthusiasts. Yes, I am including the simple, closed watercooling kits from corsair and the like.

At stock speeds/voltage - most of the time the stock heatsink is fine. If a small case/bad airflow/or other issue like this then I would recommend something like the coolermaster hyper 212+ evo (or whatever they have renamed it this week) as for $40, or less, you get most of the performance of a high end heatsink and much better temps than the stock one.

Thermal compound - I usually dip a q-tip swab in rubbing alcohol and carefully remove what's on the CPU with that and a piece of scrap cloth. You don't need much alcohol - just wet enough to help loosen the gunk off the CPU - not so much that it runs off and onto the motherboard.

If you don't expect to change the CPU/heatsink again - the stock stuff that comes on a new one will do. Though you will get a bit better performance if you buy some new stuff (and you will have it if you need it again). $20 will more than cover it, but as I said not needed now. You can always buy it later if you need.

LOL I am no sales person. I only suggest liquid cooling. Then stated using the 212 EVO. Considering liquid cooling woudnt be a necessity.

Agree with most, disagree with a few.

Firstly, amd chips while run hotter than intel, also have a lower thermal limit. But your close and nothing you said is wrong just could be mistakenly interpreted.

Second, your 100% correct in the liquid and air. For stock/mild overclocks, hyper 212 is best in class price/performance under the $110 noctura something or other beast of a tower cooler. Corsair H55 does a good job and compares closely to the 212, but at a $55 on sale $75 reg price. So if tower allows, choice is a given there shown by price.

If you want to get higher overclocks, that's where the huge tower noctura (again don't remember exact name) for $100 will do great, otherwise corsair H100/110/105/100i ect all do about the same.

And then yes, anything involving massive enthousiest class overclocks will need even more, in which my cooling setup costed more than my components, which is kind of sad.

But, most importantly, air/aio (all in one) water, is personal preference. Some don't like huge air cooler sticking out, and like the sleek look of the all in one kits. While others take note that the huge air coolers cool the chips for cheaper, but all greatly increase air flow in the case, and cool the motherboard as well.

I for one don't like the huge air cooler look, but I went in knowing id do custom liquid. But if I were to stay stock speeds, id opt for the coolermaster hyper evo 212. Best thing for $30 you can do over a stock system.
