756933 2009-03-16 08:59:00 Hi, my query is to do with effective case cooling and fans configuration. To complicate matters I have a 8600GT silent graphics card with no fan. It has a heat pipe. This appears to rely on air movement to/from case through pipe.
Whats the best fan layout?
In the front ....and in the side (for cpu).?
Out the back... and out the power supply.?

PSU has large fan, probably a 6inch.
Other 3 fans are 80mm

Currently temps are core 47, GPU 50, Mobo 30 & 45, hdd1 39, hdd2 40
Some of these, especially cpu rise when working hard.
How should I determine safe operating temp range? Any views please?

756934 2009-03-16 09:04:00 Well as long as it stays on, its safe :p

You'll soon find out if its hot / overheats

It'll shut down

This case has only got 2 fans at the back 8 or 12mm i think, And the duct thing for the CPU on the side.

It does take 2 fans at the front, but I havent bothered putting any in yet

THE GPU in this gets pretty hot too, about 48-50. It doesnt have a fan either

756935 2009-03-16 09:21:00 For temps I am using Speedfan 4.38 beta 10.
The thing about it is the graphic "flame" it has when the temp hits 50C or higher. Below 50 is green tick or blue if it's really cool.
Actually this case hasn't got the side entry funnel for the cpu but I am seriously considering putting one in. Looks like a great idea.

756936 2009-03-16 09:28:00 If 50 is only showing for the CPU, I wouldnt worry about it.

This GPU usually hangs around 48-50, it hasnt blown up YET.

And it is a beta, so may or may not be accurate

756937 2009-03-16 10:24:00 And it is a beta, so may or may not be accurateFunny you should say that,because it reports temp3 as minus 128. That's safely ignored!
The other temps are all very sensitive to the work load.

756938 2009-03-16 10:38:00 Whats the CPU?

Because if its an Intel Quad, the temp sensor on some of these are bung / stuffed anyway .

So, it doesnt / wont matter what program you use to monitor the CPU temp, it'll be wrong

Oops my previous post should read GPU, NOT CPU

756939 2009-03-16 10:46:00 So what case do you have?
The reason I ask is as do not know without going through all earlier posts made by you.

756940 2009-03-16 11:17:00 So what case do you have?
Older unbranded ATX. Has facility for 1 fan front & 1 back. Actually I have other cases I could use but none have the side cpu vent. I might have to improvise.

The board has cool n quiet which can make quite a difference to the noise level.

756941 2009-03-16 23:23:00 2 fans at the front of the case and 1 at the back.

Make sure no cables are blocking the airflow to the HSF for the CPU

756942 2009-03-17 07:02:00 Speedy...the cpu is a phenom II.

I've been studying fans, looking at db ratings. It seems that yes I can get a quiet fan but they don't appear to pump the quantity of air as a higher db one does.
I have used the trick of running 12v fans on lower voltage. It worked great through winter on my old PC, but when the warm weather arrived it was time to restore 12V to the fan again.
Has anyone put a fan in the base panel of the PC case? A decent size fan would fit 120 - 150mm. Same could be for the top.... or is there a drawback to the idea?
