2x80mm or 1x 120mm?

[Hicks12]

well my case is an oldish chieftec and with a new case like the 900 out of my price range i was thinking perhaps too make it quieter etc by using the akasa 80---> 120mm fan mount. Would it be better to have 1 120mm fan or 2x 80mm fans? for cooling and sound.
And if the 120mm fan is better, recommendations for around £5?
Was also thinking of getting a 140mm fan mount for 3x 5.2" bays

worth it? And what 14cm fan would you guys recommend? the one i was going to get is out of stock.
Currently my case has 2 rear 80mm fans and 2 front 80mm and 1 side 92mm fan.

And as a side note, any1 selling an antec 900 cheap?XD if it is <£50 i would think of buying it off you .

Thanks.

The Nexus 120mm case fan is cheap and quiet and will push enough air

Whether this is adequate cooling really depends on what you have in the case
and what CPU cooler /PSU you have

If you replace the front and rear 80mm fans with one 120mm fan each you will certainly reduce the noise a great deal.

[Hicks12]

cant replace the front ones as they are on single mounts like under the hard drive mounts and 1 is in the hard drive mount.

I have an arctic cooler 7 for cpu and a xclio 700W psu(modular) specs are in my system bit

for buying an antec 900 check the classified/market place


as for 80mm/120mm it depends on the fans. I'd rather have my Xclio 120mm fan than two homemade 80mm fans.

however, if you're budget is ~&#163;5-6 I can see you getting 2 of these:

or 2 of these (for &#163;7):

or 1 of these (120mm):

Just from numbers you can see that the two models of 80mm fan are the same model, with different LEDs. Until about another &#163;1/fan or so, all Akasa fans are pretty much identical, with minor changes here and there to airflow.

However, The 120mm fan, with no LEDs, is stated as being about 1/3 or 1/4 as loud as the the two 80mm fans.

However, numbers being numbers, it also shows an airflow of approximately 1/2 that of either of the two 80mm models combined together.


You do save some money though!

It's up to you, if you want more noise but more airflow stick with two 80mm fans. For slightly less airflow and a lot less noise go to 120mm.

My Xclio is stated at running at 40db and I haven't noticed it yet (probably due to headphones ) but it's got higher airflow than either of the two models stated here.

If I could remember the model I'd tell you it, but I can't so :S



EDIT
I'd trawl through the non-asaka ones for you, but it's a little taxing trying to do homework, talk on MSN and post on the forum all the same time. If I have the spare time (or set of hands) later I'll come back and post some non-asaka fans

Given you are just looking at case temp and you already have plenty of other fans, iwould replace the 2 80mm rear fans with one 120mm one.

For quiet fans you can't beat Nexus or Scythe. Notua are also good but more than &#163;5 (closer to &#163;12).

Note that noise level specs don't mean much unless they say how it was measured e.g. at what distance and in open area or within a case etc. Always go with idenpendently tested specs rather than manufacturer specs with regard to noise/airflow

Also to reduce noise, you may not even need any front fans. Track the temps with these disconnected and see what increase you get.

I used to have two fron 80mm fans, one 80mm rear exhaust and one 80mm fan on top of the case in addition to CPU cooler and PSU fans. Heck of a lot of noise.

Stripped down now to just one rear 80mm silent fan ( Noctua) and case temp only increased a few degrees but it is inaudible.

[Hicks12]

will give that a try as i did try with the 2 back ones off earlier with about 2-4C increase i think.

Ive already got some 80mm fans but thanks for looking .

Will update here soon.

THose orange ones good? better than yate loons?

[Hicks12]

well took out one of my front fans(was the noisiest) and replaced with a extremely quiet cooler master fan i have and i set the rest too medium speed and its pretty quiet also too the 92mm on the side off(that was extremely loud) and i believe the temps increased about 1-2C.
May reconsider buying that adaptor+fan as it seems good enough @ 40C motherboard(asus probe says) at idle, will see on load.

I was thinking of getting a new dvd rw drive sata one too replace my ide one too improve airflow, got a good one from yesterday for &#163;12.90 now, suggestions on what too buy too bump up too &#163;20? already decided on getting 12" green Cathodes and they are &#163;4, &#163;3 things?

1 x 120mm everytime.

2 x 80mm will produce alot more noise to get effective cooling.

[Hicks12]

will buy a 12cm fan +mount too bump price anyways xD.
Does scan sell canned/compressed air? i could do with buying some.

[Ommid]

err, compressed air is crap lol, bought some from asda for like 6 quid and sorry to say it suuked

[Hicks12]

what would u recommend? xD hard to get in between 2mm gaps of metal .

check the reviews and independent measurement here:

Never tried a Yate Loon so can't compare

Take the out and use a dry tooth brush.

[Das Capitolin]

I think that if noise is an issue, than a single 120mm fan is better for the job.
