And if the card temperature seems good(65°/72°) the CPU temperature with the fan full running still always about 65°, alone on sea ! Imagine in convoy...

Thanks to the link, i gonna try it.

EDIT

And thanks to your fast answers mates.

You're dumping all that heat into the case, so what do you expect? You need more fans. Look to replace the fanless design with a fan based design too. I'd suggest copper due to its mass. Copper is less efficient than aluminum, but the same size copper compared to the same size aluminum packs 3 times the mass so it will dissipate much much more heat. It will also have a more controlled heat.

Case fans should solve your CPU problem.

www.coolerguys.com is a great place to find silent fans. If you want to hear the fans prior to purchase, www.silentpcreview.com has all the fans in MP3 format - at least the silent ones.

SHORT TERM SOLUTION:
leave the case cover off for a bit.

PS. The wattage draw on the video card will give you an estimate on heat generation. A 4870 will draw 120-140 Watts. The one you have draws less then half that, so the best way to look at this is that you have a low heat card, but you still have poor air circulation.

Hi,

The box is always open, I've removed the lateral panel.
A little fan ventilates the graphic card between the GC and the CPU.

Your suggestion about the power make me think: my power box* is a no name power box about 350 watts. Do you think it's enough to this card ?

For the rest, I've make a test yesterday in the Curacao mission.
With the standard settings:

75 fps everywhere if alone on sea, no one freeze.
55 fps near the little convoy.
15 fps when tankers burns.
CPU fan was turning but not to much.

But at night inside Curacao harbor, all ships open their projectors and the frame rate go down at 001 fps !!

Back on the dekstop to watch the temperatures was corrects: 68.6°c for the CPU and 66.5°c for the GC.

I still really desperate 'cause it's not comfortable to play.

@arclight: sorry, I misunderstood what you mean.

*: I mean "electrical power box" witch gives the voltage to the system, I don't know the right word in English. Sorry.

Hmm. Try a different driver rev. The 4670 should easily chew through anything that the SH series can throw at it. The only thought is the lights are being software rendered when they should be HW rendered. Usually a driver can fix that.

I might be off, but 350W noname, might be too little, but symptons of this are usually different.

Its been a while since I have had less than 500W...

Will anybody else comment on the PSU?

[Arclight]

400W is recommended for that card, so technically the PSU is underpowered. What matters though is how many Amps it delivers on the 12v line; a 350W PSU doesn't deliver all of it's power on the 12v, but divides it over multiple lines. A 2000W PSU that only gives 2A on 12v will fail to power even the most basic system (extreme example, but you get the point).

No-name PSUs are never a good idea because the quality of current they deliver may be bad. A 12V line that actually carries 11.5V or 12.5V may well damage components and reduce the lifespan of the whole system. Because no-name PSUs usually are cheaper because they use cheap components, they are more inclined to have a reduced lifespan. Even if the quality falls within specifications when it is new, it might degrade over time and cause trouble down the road.

My brother had cheap PSU (also 350W). He upgraded from integrated graphics to add-in card (8600GT). 1 month later his HD started to go, month after that DVD-drive began malfunctioning, not to mention random problems he was having (crashes and freezes). Put in an Antec Earthwatts 380W (and replaced HD), not a spectacular PSU but quality. All problems solved and nothing popped up since then.

An old cpu: Pentium 4 540 3.2 Ghz

Bottle neck ... with new video card

Need a cpu/fan upgrade plus the power supply

will your motherboard handle an upgrade?

[SUBMAN1]

A 4670 will work fine on a 350 Watt PSU. The next jump will not - A 4770 requires a 400 Watt.
