Good day everyone,

As I'm not good in computer stuff. I would like to ask for assistance. Im playing Dota2 on my PC. It has an i3 4130 and r9 270x. Most of the time I get crashes. I've monitored the temperature of the cpu and it turns out that it reaches 80 degree celcius and higher. Im planning to replace my stock cpu cooler with a CM t2 mini and adding 4 case fans. I have a H81m-c motherboard and a thermaltake commander-ll case. What are the things that I have to consider before buying these fans? Thanks!

I did a chart a while ago comparing some of the most popular fans.
Quality fans come with good pressure and high airflow.

In the 120mm range the best fans are Noctuas & Cougar CFDs for performance/noise ratio
In the 140mm range it's again Noctua & Phanteks

2 case fans should suffice.
If your cpu runs that hot there's also a chance the cooler isn't seated properly, thermal paste is all gone or there are a lot of obstacles blocking the airflow (for example messy cable management)
Also top blow coolers require a good exhaust fan

IMHO, you don't need that many fans.
1 front intake and 1 rear/top exhaust should be enough for your system.
things to consider is the type of the fan. there are airflow optimized fans and static pressure optimized fans.
first work great in open environment, second work great on radiators, heatsinks and any other environment with "obstacles" to airflow.
the absolutely best fans would be noctua NF-F or Noctua NF-P fans as they are great at both + produce less noise. they are also very durable and work for many years.
