pci fan exhaust idea.

[computerwiz1101]

so i want to expel as much hot air as possible from my computer since it will be on 24/7 with about 5 hours doing heavy work..i was looking for ideas and found this on a list somewhere...https://www.amazon.com/Antec-Super-Cyclone-Blower-Expansion/dp/B0007MGEO2/ref=sr_1_6?ie=UTF8&qid=1508252507&sr=8-6&keywords=pci+fan it looks fine and if it works that be awesome but i'm doubting it for the price..thoughts on something else besides 2 fans? it's going to cool 3 HDD and a integrated cpu asrock j3455

To me it seems like a waste when 120mm case fans set to exhaust does the job 3 times better. Unless you're using literally all of your case fans this isn't worth it. Also an integrated CPU isn't going to output much heat to begin with. Just add a fan or two and that level of airflow will be enough to keep the inside of the case cool.

right in just remember the last time i had a cpu like this after like a hour of normal work the heatsink was burning to the touch u could feel the heat coming off it almost lol..corse this was back when dell made everyones pc lol, next i gotta figure out if i should install my 200 somthing mm fan or use a 120/140 directly on the HDD decisions decisions

Those things don't push much air at all. Also 3 hhd's + all the other stuff is not going to be hard too cool at all just a decent airflow in the case will be more than good enough.

Slot cooling isn't particularly efficient and for a 10W CPU, a single rear exhaust fan at its lowest speed setting should be vastly sufficient. Only intake fans for the HDDs and no exhaust should be fine as well.

yeah i have two 120/140 noctua fans i'm gonna install!

That's intake fan. Meant to help cooling graphics cards.
Not very effective and rather loud.

Stick with standard cooling guidelines:

• intake fan in the front;
  exhaust fan at the back;
  positive pressure to minimize dust buildup.

When it comes to fans and airflow (all fluid flow actually), there are two simple rules.

• 
  ■Bigger is better
  ■Straighter is better

A 120mm fan is better than two 85mm fans despite having about the same surface area (14400 mm^2 vs 14450 mm^2). Airflow encounters more resistance at the hub and the ducts (edges). And the larger fan has more airflow further from these resistance-inducing components. A single large fan is also more energy efficient than two smaller fans, which in turn are more efficient than four (same is true for airplane engines, ship propellers, which is why the A340, 747, A380 are all losing out to newer twin engine aircraft). The main reason for having more than one fan is redundancy - so you'll still have airflow if a fan fails.

Also, in a one small vs one large fan scenario, the larger fan can push the same volume of air at a lower velocity, meaning it'll run quieter at a lower RPM.

Likewise, any any bends add resistance. This decreases airflow, increases noise and power consumption. So a simple fan sitting in the side of your case which moves air from one side to the other is best.

Length of tubing also adds resistance, but not significantly at the distances within a PC case.

so i should get my 200mm huge fan over a 120/140 fan thats almost directly on the hdd? if it dosent make sense just say so lol

If I tell you it doesn't make sense, next time you encounter this problem you'll have to ask us again.

If I explain why it doesn't make sense, next time you encounter this problem you'll be able to figure out the answer by yourself. Better yet you'll be able to help someone else who has the same problem.

something like this might help 😀

Once you go beyond 120mm, problems with balance causing vibrations at various speeds become increasingly common due to the extra leverage magnifying any balance issues the fan blades may have. I ended up disconnecting the 140mm fan in my case because it produces an annoying rumble noise at its ~800RPM low speed. The rumble goes away at higher speeds that the fan is balanced at but then the airflow noise becomes annoying and the negative pressure it creates in the case renders the intake filters and fans ineffective.

For pci i have this item

The position can be changed and the fans can be changed. The package has short and long screws.

For hdds there is from Deep Cool

Those things only lower them by a few degrees since the hdd's don't have a heatsink to transfer the heat to and be efficiently dissapated. Still just a steady stream of slow moving fresh air will keep hdd's cool.
