We’ll take a closer look at three such technologies that fall under the headings of Centrino, Viiv, and vPro, respectively.

Chassis Airflow
Date Issued: 20th Oct 2008

The modern PC is potentially a mass of heat output and heat production hot spots. With CPUs rated at more than 100W of heat output, single graphics boards carrying similar ratings (and people want to run two!), multiple hard drives the norm, lots of memory and mainboards covered in heatpipes to combat toasty core logic and PWM circuits, a PC appreciably warming up a room when it’s working hard is no joke.

Questions & Answers

Would this fit a MSI Z87-GD65?

As I do not currently own this motherboard I'm unable to find the CPU cooler dimensions, therefore am asking this question: Will this cooler fit? And if so, is it capable of Cooling my I5 4670?
Asked by: Jbutton
I use this cooler on my 4690K no problems so it will work just fine on your mate. The cooler is very low profile and punches way above its weight! Brilliant from Noctua

Hi, Will this be sufficient to cool an Intell I7 4770k (LN50784)? Or will i need something bigger?
Asked by: JR1993
it would probably cool the cpu better than the stock intel cooler, but if you are thinking of overclocking you will need something bigger

Is this recommended for a MATX case?

I use a Corsair Obsidian 350D and want a new, quieter cpu cooler for gaming. I assume that although this is designed for ITX that it will work just fine in MATX?
Asked by: Christrix
Hi, I would recommend checking the socket compatibility of your CPU, you can find the compatibility list below. Socket compatibility: Intel LGA1150, LGA1151, LGA1155, LGA1156, AMD AM4 with NM-AM4-L9aL9i To see if this would fit inside your case I would recommend checking the dimensions below: Height (with fan) 37 mm Width (with fan) 95 mm Depth (with fan) 95 mm Kind Regards,
