Some AMD 970 chipset motherboards may need a BIOS update prior to using Vishera CPUs

You're back! And even though that there are 7 slots, how many do you think is enough? And is the stock exhaust fan any good? And for the CPU, do I need another cooler or is the stock one good enough? I want a somewhat quiet computer but I don't want it to be that hot. Thanks in advance!
 


The stock CPU cooler is good for the i3. You'll have to see how good your graphics card temps are. I tend to populate all fan slots, but you might need to buy a fan controller if you do that since there won't be enough built-in fan controllers on the motherboard for all those fans. You could run them straight to the PSU but then they will be at 100% all of the time and it will sound like a jet engine. From what others have told me, the stock Cougar fan on the MX300 is good. More fans at low RPM will be quieter than just 1-2 at high RPM, and push more air.
 


I'm also a fan of those Sickleflows. They are my budget go-to fans. They provide massive air pressure and come in smoke, green, blue, or red LED. But, I would wait and see how good your graphics card temps are before dropping $$$ on 7-8 aftermarket case fans.
 
When you say the Sickleflow, do you mean this? http://www.coolermaster.com/cooling/case-fan/sickleflow-120-2000rpm-blue-led/
Or do you mean the one meteor recommended me?
How many do you think I should start with?
 
The Sickleflows are the same as the ones that Meteors showed you, and the same as the ones above ^^

The difference is that Meteors showed you the plain smoke version (no LED) and you linked the blue LED version. I personally have owned the green LED version and the red LED version, and also the rebranded Rosewill version (manufactured by Cooler Master). All good fans but at full speed (2000RPM) they make a good bit of noise with all that air pressure (a swoosh sound) so most people don't run them at full speed unless running some benchmarks.

How many? Up to you. I prefer at least one fan exhausting in the rear, and one front and one side intake.
 
Well doesn't the case already comes with an exhaust? And which is more important? Intake or exhaust? And my other question is that even though there is an exhaust in the case itself, can I add more exhausts?
 
It has an exhaust. You want at least slighty more intake pressure so that your dust filters (on the intakes) work properly. With negative pressure, dust just accumulates randomly in the case and on the CPU and graphics card heatsinks especially.
 
The Sickleflow works for both exhausting and I taking right? If so, I'll have 2 intake and 1 more exhaust with the one that comes with the case. Is that ok?
And I didn't really understand the negative pressure thing and the dust
 


Should be fine.

You want at least slightly more positive case pressure so that dust hits the dust filters instead of entering random crevices.

The way to test is called "the tissue test". Take a piece of tissue and hold it near an opening in the case (one without a fan). If it sticks then you have negative pressure, but if it blows off then you have positive pressure.
