CPU Coolers and GPU

I would look for Zalman coolers, those I have successfully used for 2 of my last PCs - both GPU and CPU. And they are of a good quality, too.
For up to date recommendations on exact models, I would google it.

If it's your first time applying thermal paste, better watch out for some instructions (probably they have some on youtube). It's not really difficult to do.

And for attaching it onto GPU, I used to do that when video cards did not come boxed, e.g. 6600GT. That way, the process is no different from applying it to CPU. If the video card is boxed (has a cover with integrated cooler), I would look for instructions on the internet whether it is possible to remove the cover and proceed. Be careful about this though, don't proceed if you are not sure.

Ok gotcha ;) thanks

For CPU coolers, I would recommend a Cooler Master Hyper 212 if on a budget or Noctua NH-D14/Phantek if you want the best air cooling.

Razer Blackwidow is a terrible mechanical for the price.

Look at one of these brands instead: Filco, WASD, Das, Ducky, Rosewill, Leopold. KBC and Cooler Master are also decent.

Get a Corsair Hydro H100 or H80 for CPU. They are great, easy to use and perform well for the price.

Also, if you do not know how to use thermal paste or how to apply a GPU cooler, I would stick to stock cooling on the GPU and just get something for the CPU, like the Corsair water coolers.

I use cooler master hyper TX3 cpu cooler and keeps my temps cool at 29c with my cpu overclocked from 3.0GHz to 3.6GHz

95% of the time I work with a dead video card I find that the killer was dust caked into narrow ventilation pathways. What happens is dust accumulates into the lanes and creates a seal not allowing air to pass through the hard heats up and micro-fractures occur and card dies. Most people are not comfortable with disassembling a video card to clean it so that is why I always suggest to use open style coolers that simply bounce air off exposed fins to expel heat. This way you can also see if dust is an issue and clean it if you have a case window. I just recently had a XFX 9600 GSO from a neighbor die this way.

This is the type of cooler you should avoid buying
That is unless you are happy buying video cards yearly to stay up to date.. but then you would likely stick with a stock cooler.

For CPU coolers, generally look for something with lots of copper and your set if you matched it to your CPU socket type.

Hyper 212 EVO for great price/performance cooling. And if you're not doing insanely high OC'ing, there's no reason to get aftermarket GPU cooling
