Hi Folks,

I am thinking of adding another rad to my loop. I think my temps are ok at the moment but if I have space for another rad then why not.

Currently I have an overclocked GTX280 and a Q9550 @ 4Ghz cooled with a PA120.2. under small fft prime the Q9550 doesn't go about 60 degrees ( 2 of the cores don't got above 55 degrees).

I have spave to add a single thickness 120mm rad like the XSPC RS120. I don't think I could fit a double thickness rad in.

Would it be worth it? Would it lower my temps any more?

Here is a picture of my case, I want to put it by the bottom fan at the back so my loop would go

120.2> res > pump > 120mm rad > cpu > gpu > 120.2

Thanks
 
What I'd really want is for as much heat as possible to be drawn out of the loop before the CPU as it is the hottest component. The GPU sits at around 40-45 under load and is about as overclocked as it can get. The CPU hits 60 deg under load so I though if I there were more ways for the water to lose heat before it got to the cpu it would being the temp down more.
 
The fan set up is front and back bottom fans are drawing cool air in, fans above rad are drawing air out. Hot air rises so this is probably the best set up.

The side of my case is normally on, I just took it off in this case to show what my loop looks like at the mo.
 
My one worry about changing the direction of the fans is that I may lose airflow over my northbridge so I'd sacrfice that by having a cooler cpu. With the mother board currently running at 470 fsb and maybe with some new ram even more I'd want so air over the NB to keep it cool without having to add any more fans.
 
Ok,

What I am going to do is change the fans around and see if it makes a difference. Since I'll be doing that ( which is pretty tricky in a small case) I might bleed the system as well and add another rad at the same (hopefully on its way to me from ocuk) and see what difference it makes.

I am getting some faster ram too so hopefully I'll have a bit more room temperature wise to push the cpu a bit harder.

I'll post a new thread tomorrow with some pictures etc.

The plan is, temps as it is,

temps with the fans turned around

temps with a new rad

and temps after further overclock.
 
Gutted! Put my new rad in and changed the fans round but I didnt like it, I could feel the air coming back out of the top of the case even though the fans we blowing in.

I decided to change it round again and in doing so put a ******* hole in the rad! Another one is on order so I'm going to have to wait until mid week until I get my hands on it.

So close but yet so far!
 
Cheers brad, sent a reply

Decided to change things around while I have it all apart and drained again so along with a new rad I am getting some new hose and anti kink coils (going for black tubing and yellow anti kink) I'm getting a new top for the pump and a separate resevoir as I think having the res on top of the pump adds to the vibration and so noise. I also got a lapping kit for the CPU and the CPU block so hopefully I can shave a few more degrees off. Last thing I got was some mx-2 thermal compound so hopefully that might help as well.
