X1 12CM or X2 8CM?

2-Bit-Geek · Mar 6, 2009

Just wondering about cooling again, I had a heat issue solved by more fans but then I got a new CPU HS&F which made temps go up again. Somehow I managed to fix the problam by taking out some of the extra fans :confused

Here is my current cooling setup:

Case: http://jeantech.com/nitro.htm
Front top down: DVD RW, 12CM FAN:http://www.akasa.co.uk/, 12CM stock (Blue L.E.D) fan, DVD ROM.
Rear: 12CM stock (blue L.E.D).

CPU: http://www.akasa.co.uk/

GPU: http://www.sapphiretech.com/us/products/products_overview.php?gpid=250&grp=3
Stock cooling

The temps I am getting are ok, I just wondered if X2 8cm case fans would work better than X1 12CM case fan bearing in mind one of those 8CM fans has speed control: http://www.akasa.co.uk/.

Edit: yes akasa website sux for links, your looking for the Akasa Revo AK-925 CPU cooler & the L.E.D case fan 8cm,
AK-170CC-4RABSC

Hi

What are your temps?

2x80mm fans in the same space as a 120mm fan would push more air than that of a 120mm as 80mms may push less air say 25CFM to a 120mm at 35CFM (rough figures) but 2x80mm would be pushing 50CFM so more airflow but at a noiser rate.

Will have to balance front and rear fans so that whats coming in is same as whats going out, or have the 2x80s in the rear expleeling more than whats coming in, but balances airflow is best imo.

What direction is the CPU HSF fans direction of airflow, and what is rear fans direction as both should be pushing air from front of case out of the back.

Well after the fan switch over I have a GPU temp of 44C idle (CCC), that is the lowest the spedometer style gauge goes :-D (it will report lower temps but the needle won't move).

CPU temp is 40C idle (PC Probe II), and thats with an Akasa Revo AK-925, I am gonna get some arctic silver for it, because I think I put a little too much Akasa compound on.

It's hard to describe the fan layout :confused

Here goes:

Case front: X2 12CM stock Jeantech, pulling air in.

PSU: 12CM fan, not sure if it pushes or pulls:confused, I asume it pulls as it has a mesh plate on the putside face.

CPU: Akasa Revo stands upright heatsink wise & the 9CM fan on it points down.

GPU: Stock Sapphire 4870 1GB HS&F, it pulls air in & along the GPU then it is expelled outside the case.

Case rear: X2 8cm fans Akasa, 1 is blue @ 2500RPM, 2 is multicolour @ 2000-3800RPM with speed control.

I also used an old Akasa system blower inside the case to blow cold air into the open end of the GPU to help cool it, I removed the drive cover. It spins @ 2000RPM it's airflow is pretty good @ 35.12 CFM :-D

Hi

That CPU temp of 40c is great, wouldnt worry too much, the PSU fans generally expel air out of the back. Front fans pulling air in are fine, the Akaska Revo, thought the fan on this is vertical and blew air through the radiator grill heat sink? and will either be in the direction of the PSU fan or out back of case via the rear fans with its airflow, in which the rear fans should be expelling air out back of case (will be able to feel the draft of air if pop hand close to the fans at rear of case).

But dont think heat wise you have any major issues, woudl if possible tidy up any internal cables so they are routed out of the path of any fans as much as possible.

I am very proud of my AKASA Revo, at first I though it was crap. But with a little effort & patience I got 40C out of it which is good for a Phenom :-D

AMD & Overheat are often highly Google'able words LOL

The Revo is indeed a verticle setup, it sucks air in from below & pushes it through the massive radiator towards the PSU with not too much clearance.

Oh there is plenty of airflow, I just wish I could find out what speed the stock 12CM fans ran on my Jeantech Nitro. They are awesome fans, very high airflow. I say this because I got a 12cm AKASA fan & there was hardly any noticable airflow to speak of compared to the Jeantech ones. However the two Akasa 8CM fans on the back are great, 2500RPM & 2000-3800RPM :-D

As for tidying up the case, I found it made no differance last time. It just annoyed my when I wanted to move/remove or replace anything. Taking my HDD's out is difficult enough with this case being 5.25" drive bays top to bottom needing HDD brakets.
