Basically I noticed when going to a buddys house him and his brother both had northbridge coolers, there PC's are a few years older than my build(about 3years for my buddy and about 4-5 for his brother) Mine build just last year. I was wondering if it would be worth getting a northbridge cooler for my setup, I haven't checked temperatures via ASUS thermal radar under loads but it had me wondering about if it would be useful?
Here's a picture of the inside of my case to get the flow of my system:
Since you cant really see the northbridge in the picture about heres a picture of a motherboard(same exact one) in the same position your seeing mine the the first picture:
Figure i let the motherboard experts take a poke at this.
Also would it be a good choice to have a cooler on the southbridge?
You got a heatsink which is enough with proper airflow in the case. Many older chipsets were hotter and needed additional fan for proper cooling. With progress electronics are getting smaller more energy efficient and therefore not producing as much heat. I would not worry about it.
