[OCCLUB] COrsair H80 review. - Page 10

post #91 of 114
Any decent case, without obvious obstructions or terrible airflow, will renew the outside air into itself completely every few seconds.
Think for a second on how much 60 CUBIC FEET PER MINUTE is...
Now figure out how many cubic feet your case has. Now, since it's not an empty box, the CFM will be lower, but even if it's 30CFM total I/O airflow, and a large case has about 2-3 cubic feet of area, you are effectively renewing all the air in the case every 10 seconds or so, minus circulatory pockets.

And to Freedomdwarf: Was the H80#1 pull ONLY, with 2 fans? It just seems like WAY too much of a temp difference otherwise.

I like D14 because I have enough room, and it is basically silent.

Hmm I thought some people here on OCN were getting better temps than the D14. Still the temps are close enough I that I would take the H80 over the D14 assuming I could get them for close to the same price. The H80 seems to be a little more now but I have also seen a few sales on it.

I thought I explained my fan orientation quite clearly.
The H80#1 test was the 'standard' setup as per the Corsair instructions - ie, both fans pulling in air into the chassis so that the outside one (nearest the rear panel vent/grille) was 'pushing' air into the radiator from outside and the inner one 'pulling' that air through the radiator and into the chassis.
The H80#2 test was with the fans oriented the opposite way round (both reversed direction) - ie, the inner one now 'pushing' air into the radiator from the chassis and the outer one 'pulling' air through the radiator and exhausting through the case vent/grille.

The H80 radiator assembly replaced my two 8cm exhaust case fans mounted on the rear panel vent/grille which were connected via 12v Molex, not via PWM headers. That leaves just *one* independant 8cm fan exhausting on the side panel.


It wouldn't make any sense for both fans to be 'pushing' into the radiator or 'pulling' out from the radiator - they would be working against each other.
Unlike the H100 which has a full-sized 240mm radiator, the H80 is just 120mm and the fans cover the whole radiator fin area - there is no spare space or gap for other air flow other than what the fans provide it. With the H100 you could 'pull' at the top and 'push at the bottom and various other combinations but you don't have those options with the H80 because of its size. I can't fit a H100 in my case as I don't have the room for a full-sized 120mm setup.

Sorry, I once again, for some weird reason, thought of the H100 with the 2 included fans. I wasn't paying enough attention.

@ Spicy61 -

Quite a few review sites put the H80 as better performance than the Noctua D14's - the D14's have now been out-classed by the H80.
The down-side is the H80 fans are definitely noisier than the D14. But as I mentioned earlier, unless you work in a library or have the need to have your rig almost silent, the H80 is the better product of the two - and it's not so big or heavy!
In my rig, the 'balanced' profile setting for the H80 is no noisier than the standard stock air cooler that came with the processor with the two case fans I had. So from that point of view I'm well happy with it.

@ Accuracy158 -

Those whopping great air coolers like the V8/V10 or the D14 are very quiet for the cooling capacity they provide and I can't knock them for what they do and for the price.
However, their sheer size and weight (plus, I think the D14 is downright ugly) puts some ridiculous contraints on a lot of consumers. As I quoted earlier, a D14 with both fans fitted is a whopping 1.2+Kg hanging sideways from the CPU mount! To me, that's just unacceptable and as many review sites mentioned, it could lead to micro cracks in the motherboard leading to instability and eventual death of it. You also have to consider that some motherboards just can't accept such a huge air cooler without losing use of some of the Ram slots or other motherboard things attached to it. Those considerations aside, you also have to think that unless your case is wide enough it just might not fit!
That's why, even though the V8 or D14 is quieter in operation, I would opt for a H80 over a huge air-cooler any day - I don't fancy having to replace my motherboard in a few years because the cooler has damaged it.

Just grabbed an H80 @ Amazon for $91. Looking forward to putting my ram sinks back on due to my NH-D14's wide girth.

Just bought mine about 30 minutes ago along with a lot of my sig rig parts! So excited.
