Are stock fans enough?

[Tobisuff]

My case is Nxzt 410, (u can recomend me others) and i was wondering if tje stock coolers are enough to cool my 16gb of ram, gtx 1070 and i7 7700 (non K)
Are they enough or should i get an additional cooler?
What about overclockimg?
And i7 7700k?

The NZXT 410 comes with 3 decent stock fans (1x 120mm at front intake, 1x 120mm at rear exhaust, and 1x 140mm at top exhaust). You might want to add an additional 120mm front intake.

The test video above shows that:
0 case fans (CPU air cooler only): CPU = 71*C | GPU = 92*C
1 front intake fan + 1 rear exhaust fan: CPU = 60*C | GPU = 79*C
2 front intake fans + 1 rear exhaust fan: CPU = 58*C | GPU = 77*C
2 front intake fans + 1 rear exhaust fan + 1 top exhaust fan: CPU = 55*C | GPU =76*C
2 front intake fans + 1 rear exhaust fan + 2 top exhaust fans: CPU = 55*C | GPU = 76*C

Notice that after adding a top exhaust fan to the 4 case fans, there were no difference in CPU/GPU temperature.

For the locked/non-OC i7-7700 (non-K), even the included Intel Stock Cooler will suffice (you can still get an aftermarket cooler if you want better looks and lower noise), but the stock can handle the thermal dissipation as the i7-7700 has low TDP.

As the i7-7700K (which doesn't come with a stock cooler and has higher TDP), as well as OC'ing it, the CPU cooler should be a good-quality one to effectively dissipate heat generated. Recommended aftermarket CPU coolers such as Cryorig H7 or H5 and be quiet! Dark Rock 3 are great choices.

2 front intake fans + 1 rear exhaust fan: CPU = 58*C | GPU = 77*C

That's a fine solution ... the reasoin yoiu only

First let's cover the number.

CPU (90 watts) + GPU (180 watts) + RAM (5 watts) + 45 (everything else) = 320 watts.

For each 120mm fan running up to 1200 rpm, you can sit in a quiet room with one fan for each 50 - 75 watts.
For each 140mm fan running up to 1200 rpm, you can sit in a quiet room with one fan for each 75 - 100 watts.

So the default set up leaves you with (2) 120s a (1) 140 and if we do tot he limit above, that covers 250 watts, so you a bit short. The problem however is this. Lets use the 120mm as base value of 1 ... that gives the 140mm a value of 1.33

So you have the equivalent of 1 + 1.33 fans blowing out with no restriction ... and you have 1 blowing in with a dust filter that when you don't clean it can restrct flow by as much as a third. leaving you with 0.67 coming in

With 2.33 going out and just 0.67 coming in you have about 3.5 times the air blowing out as in. In order to get out, it has to come in somewhere and it's coming in from every open space from every nook and cranny available

But if you look at the case design, the openings which have the least air resistance ate the vented slot covers and case grille on the rear of the case....and the top 140mm mount.

So if you don't do anything, here's what is happening.....

1. Some of the hot air exhausted by the top fan is getting sucked right back down inside the case.

2. The hot air that gets exhausted from your 180 watt GPU and the hot air exhaust from your 600 watt (guess) PSU is getting sucked right back into your case thru the rear grilles.

So you are not exhausting the hot air and making it go away, just recirculating it in and out of the case. You can demonstrates this pretty easily if you like using a $40 fog machine that we use for testing ... if ya know a local garage bands, you can borrow one from them

So what is the remedy ... temporarily at least, I'd take that 140 on top and have it blow in. I don't recall if the 410 has a intake filter on top as we've mostly been using Phanteks cases of late that do.

That will give you 2.33 in (1.5 after filters dirty) and 1 in ...that will stop the hot GPU ? CPU exhaust from being blown in

What I'd go to:

(2) 120s in front as intakes
(1) 120 in bottom as intake

(1) 140mm .. It take the 140mm and move to side mount
(1) 120mm .. leave at rear

Now you have 3.33 equivalent fans blowing in, which will have a worse case 2.2 equivalent fans blowing in and 1 blowing out. The positive case pressure will force air out thru the top and rear, ending the hot exhaust being sucked back into the case problem

If ya wanna be able to test this for yaself ....
