Will a better CPU cooler help if I got bad airflow? - Page 2

post #11 of 46
Get an H80 and mount it as a back intake and keep the the front as intake. This way, you will have positive air pressure and air will leave by itself. IMO, exhausts are a waste of fan since they only change the static pressure without adding additional airflow. All they do is take out air that would leave anyway. I had 4 fans (2 intakes and 2 exhausts) and going to 4 intakes lowered my PSU and GPU temps by a few degrees while the CPU didn't change (H60 was already intake).

If you dont want to read all that: H80 as a back intake

I've been drooling at the noctua nh-d14, but will it actually help if my airflow is bad?

Thx
I love my NH-D14 running 4ghz on 1.35v under my 965 -

can we see some pictures of the inside of your case so we can drawn you an airflow diagram. and maybe flip the fans.

Yes, a better CPU cooler will help. Get the heat from the CPU as quickly as possible. Stock coolers are not very suitable for heavy tasks--regardless of the poor airflow in your case, you'll see better temps with a better cooler.

And to the contrary, I would argue that case cooling matters more for stock coolers than aftermarket coolers, as stock coolers typically blow onto the motherboard, as opposed to directing air toward a rear vent (which most aftermarket coolers do). I would argue that getting an aftermarket cooler that blows toward a rear vent would actually improve your case airflow and temps (perhaps marginally), while at the same time drastically improving your CPU temps.

no.

Hot air rises - if the intake is upper and the case is contained and there is no open grid the heat will be contained. and warm up the rest of the system.

D14 will cool your system down fine. It can even perform fairly well with no fans (although that is not the recommended configuration).

Hot air rises if it is undisturbed. Since there will still be moving air, it will in fact be flowing in a sort of circular motion around the case. I don't see it being too much a problem, but some sort of vent would be a good idea indeed.

OP if I were you, I'd save a bit and:

Get that Noctua. It's awesome and it cools really well.

And, get two high performance fans for your case. One for intake and one for exhaust. That should help you A LOT also.

Could you take some Pictures of your case so me and the People of OC.net Can Maybe find a way to mod it for better airflow?

How does an exhaust fan not contribute any additional airflow? Take it simpler, say you have a single exhaust fan and no fan on your intake vent--there's still airflow caused by the single exhaust fan.

I'm not discounting your experience with the fan configuration you mentioned, but it's entirely dependent on the case/vent setup used.

Exhaust fans can also help reduce dead pockets that might occur in a case (note--of course, this depends on the location of the fan).

OP--I forgot to mention an easier approach to see what you'll benefit from. Just run your computer with the side panel removed from your case and direct a desk fan into the case. If temps drop to tolerable temperatures, you might be able to get away with adding a case fan. If your CPU temps don't really drop that much, then you probably need a better cooler.

Wow, thanks for all the replys! (posted before i went to bed)

Well since I don't know what case I have (my brother gave it to me some years ago) I guess I should take some pictures. Its the first system I've built so I'm sure there's some simple stuff I could do.

I've only got space for 1 fan afaik (exhaust), which I recently added. It reduced my temps by 15-20 degrees, which gave my 580 gtx respectable temps at load (think i had 85c max after a few hours gaming). But my CPU reached 80 degrees, and that worries me more.

guyladouche, before I installed my exhaust fan both my GPU and CPU reached a 100 degrees. So I've tested removing the side panel and putting a desk fan there. That helped a lot, but my CPU still reached about 75c at stock speed.
