Question?

[Cobra]

When I play 2k4 or BattleFront and Warpath, my fps are exp (240) but in the game let say 4 minutes, the fps go's to 1 or 2 it lag like hell for 3 or 4 segond, and then it is ok.


It do's that 4 or 5 times in a 15 minutes games. I have all the latest drivers and stuff. Could a good sould help me please thanks. :):

It would be more helpful for someone to answer if you could give you computer specs.

In general Cobra, your system specs are fine for even the latest 3D titles but I have a simple question.

Is the extreme drop in framerates after a few minutes happening in all games or just a select few?

If it occurs with all games, then it sounds like your video card may be overheating or malfunctioning in some other way.

Cheers, Terry

My framerates drop in games when my anti-virus software starts up. Either scanning for virus or updating the definitions. Do you have this or anything else running in the background?

Thank's guy's for replying. It is only in a few games, I can't play Warpath on that PC, some maps play very well, and other's are laging like hell. In 2k4 90% of the maps play ok. Yes my anti virus is runing.


I play all those games on a AMD 6000+ whit a cheap 6800 GT 256 MB. And all the games play perfect, not even a small slowdown, or a bit of lag. It is perfect?. So if it is my video card that is heating, what should I do. I mean what to buy for that?.

In my PC case I have 11 fans, conting the vid card, and CPU's fans. If I have to put another fan, honestly I really don't kno where, it could fit. There's no place left any where in there.

So please what should I do. Thank's :):

May be too much of a "good thing" with all the fans. The proper ratio of air flow is 1.5:1, with more air being blown into the case than out. A fan blowing toward a heat producing component will be more effective than one pulling heat away. The PSU is dependent only on its own fan(s) for cooling. If starved for air flow, it can overheat.
The small DC fans on almost every PC device have one inherent failing point.. the bearing. If it is not lubed properly during manufacture, it will slow the RPM of the blades to the point where heat is not dissipated as intended.. causing component stability problems. It would be more efficient to have one or two larger case fans than many small ones, to move the same amount of air.
The most efficient method to remove heat is via a duct over the device's heat sink, exiting directly out of the PC case.. but this can be more costly. Some of the better video cards have this feature, and it works well. For the CPU, it needs better design for its air flow. The fan will suck back the warm air, raising operating temperatures. A lightweight duct over the fan's intake will ingest cooler air from farther away, and be more efficient. A styrofoam cup with the bottom cut out is ideal, and can be securely mounted with a bit of duct tape. The heat pipe cooling method works better, but is designed for only one mounting method.. with the heat radiator at the highest point. It still may require a fan to work with best efficiency. The most efficient cooling setup is the VapoChill process, where refrigeration does the cooling. But it is expensive to implement and use.

If a PC setup draws 200 watts of line power, you are generating a lot of heat within that small cabinet. In effect, it is an "oven"!

The CPU has built-in thermal limiters that slow or stop the data process when temps go beyond the normal limit. Better video cards have this feature also, but not all.
If the GPU overheats, it will stop responding.. and creates a data "logjam" that causes the entire system to slow or stop. Memory too can suffer from overheating. Some "gamer" type memory has a heat sink setup, and some pricey ones come with their own cooling fans!

For any PC work, ensure that only required programming is active in the background. This takes a load off the data stream, and gives more precedence to the intense task of gaming. Your anti-virus and Firewall shouldn't be turned off.. but any IM programming or "finder" programs should be disabled.
And ensure that your video card has the latest non-Beta drivers, plus the latest DirectX drivers from MS.

(Sorry, long post.. hope it was helpful.)

Thank's alot for the info :): yes I think that you are right all the way, I kno that inside My PC it is a oven like you say. I had to put another fan behind the case to cool the back of the case. It whas very hot there, you could have fried a egg (way of speaking of course) for the fans they are very big fans. For the CPU's I touck very big fans on each of them, they are so big that I can berrely close my case. But I will do what you have said, I will buy the proper cooling for the vid card, so it can give all the performance needed to play very well. Thank's again to you all.


God bless you :):

barely close the case?
maybe it to close, they need clearence to suck from

I'm thinking "pcwizard" or some other software to monitor temps and fan speeds. You don't have to run it all the time, but maybe monitor your next test run. I think wizard also watches speed of the processor's

I'm thinking of 3 big 120 fans (to insure enough flow) mounted on the outside, sucking thru a filter, to keep the dang dust, dirt, cathairs out of the case and stop plugging up my fins

Are you sure this is even a heat-related problem Cobra?

Even though I posed the question, I've yet to see any actual evidence that improper cooling is causing the extreme drop in framerates.

Why not test your GPU temperature during those individual games before commiting to additional fans or any other changes?

I have speak on the phone whit a BFG teck: I need a cooler on the vid card. He told me that those card run very hot. And he explain what could happend.

Like in my case.

So thank's again to you all. I will buy a cooling system for me vid card :):
