The Official OC (OverClocking) Thread!

after all the testing (ok that sounds too proffesional, faffing ) i have done im pretty sure the 4 in 3 out config i have is as good as i can get it. i was just thinking if i swapped the 1.6k fans for 4k delta ones i could adjust them to the point at which the cooling is optimal with out needing to chain my pc down (that was a joke btw) my only real concern is would i be wasting £140 on fans when its about as good as it can get with the 1.6k fans, maybe i should just swap the fan in the cpu heatsink? but would that cool the cpu any better when its reporting below ambeint already for the cpu and only 3c above for the cores?

on the other hand i think it might just be my constant need to faf with my pc that is making me look at new fans as they are the oldest things in my case.

i think i might take up bird watching or somthing to take my mind off it, loads of birds worth watching around town now the sun is out

 

Hi,
Need help finding specs(cfm and rpm) for following fan:
a12025-12cb-3bn-f1
df1202512seln
This is an LED fan (120mm) that came with my Coolermaster Mystique case but the sticker has no info on it and i tried google to no avail.
Any help would be greatly appreciated.
-thanks

 

im1992 Found your fan on a malaysian site, its specs are listed as

Rpm 2500
cfm 66.58
dB 33

 

thank you very much!
i really appreciate it

 

lets get back to the topic of the thread please. there is a cooling thread for case fans and similiar discussion.

 

ah its made by martech

sorry posted specs to another fan lol

Note that the [20.jpg]bundled 120mm fan is made by Martech (model DF1202512SELN) which is rated at 0.25A, 3W, 1600rpm and 67cfm max. Since it operates at only 1600rpm, the fan does not make too much noise

 

so this is good, right?
less rmp = less db?
but more cfm means better cooling?
-thanks

 

Just found this out by my Programming teacher.
How many people know of this Q6600 Tape mod? It bumps up the FSB to 1333 from 1066.

An interesting mod, but if you had a CPU as good as the Q6600, wouldn't you have a board that could do 1600FSB anyway?
im: 1600rpm is about as high as you want a 7-blade 120mm fan without it becoming obtrusive. For 9-blades it's about 1400rpm.
The largest fan size I recommend using where you still gain with noise to airflow is 140mm, 200mm if your noise tolerance is higher. Essentially what I mean by this is that with 140mm fans you can push out a decent volume of air and it remain quiet, the huge 20+cm fans that seem popular these days don't really push any more air for the same noise level, but at a moderate noise level they can produce a bit more, if you see what I mean.


80mm @ 22dB: 30CFM, 80mm @ 30dB: 40CFM
92mm @ 22dB: 40CFM, 92mm @ 30dB: 50CFM
120mm @ 22dB: 50CFM, 120mm @ 30dB: 70CFM
140mm @ 22dB: 55-60CFM, 140mm @ 30dB: 80CFM
200mm @ 22dB: 50CFM, 200mm @ 30dB: 110CFM
250mm @ 22dB: 60CFM, 250mm @ 30dB: 140CFM
360mm @ 22dB: 60CFM, 360mm @ 30dB: 150CFM

 

if i was to OC some DDR2 800. what would be a safe OC on them.
if i use 400mhz for my CPU (3.6ghz) and then the 2.4 multi for the mem. would give me a 960 thats a pretty good OC i would think. but is it safe?

 

Well it's not so much a question of whether it's safe, it's just if it will be stable or not. Use the correct voltage and see what happens...

 

2.2v is the required voltage. gotta take it up to +.04to get to the 2.2v no biggy there.i waws just wondering how much is safe before anything bad happens to the mem.

ive done some reading on these sticks also. they are the 16chip instead of the 8chips. but some of the info i have read the 16chips are of lesser quality than the 8chips? well not totaly lesser quality older technology

 

The mod is really for those people that get the Q6600's from Dell or some other manufacturer for cheap, like my Programming teacher who got is for $500 (Inspiron 530)

 

Ah right, that makes sense. A $500 PC with a 3Ghz Quad in it... the mind boggles!

Rob: Not sure really, I've had 16-chip sticks since I can remember, the only 8-chip single-side ones were awful...

 

thats what i thought sam. i cant really remember when talking with crucial they said something about the 1066 sticks not being double sided, but i also think they said something about them being the 16chips i doubt they can get 16chips on 1 side?? maybe i heard them wrong.
as long as i can get them to run with a 3.6ghz OC on my CPU im happy..lol

 

Well indeed. Best of luck!

 

rob,

just like with other components, the more you overvolt the memory, the hotter it will run.

 

cincyrob,

I had no issues running my G.Skill at 960MHz with the E4300. It wouldn't run that fast with the E6750 and the lower 8x CPU multi! There it seems to run out of gas about 890MHz! Must be the higher fsb affecting things!

Best Regards,
Russ

 

Hi,
But, my casing only has slots for 120mm fan.
Do you know of a cheap yet powerful dremel that can cut through the aluminum of my casing? Is it even worth it to cut a bigger hole for a 140mm or a 200mm fan?
-thanks

 

To be honest, 120s will probably do unless you're after a really quiet PC - you can still get plenty of decent airflow with them.
