Extra cooling of an OC'ed Ti200... will it help?

[Leempi]

Hey all.

Right now i have a ELSA Ti200 (4ns ram) overclocked to 220/475. However if i go any higher than that, i start to get artifacts in games such as quake3 and DAoC. Now i'm wondering, if i cut a blowhole in the side of my case opposite the AGP port, and put an 80mm fan there blowing air onto the card (as a bit of extra cooling) will this facilitate a higher overclocked setting?

I think my question is: whats causing the artifacts at higher settings? Is it a hardware limitation (i.e. the ram can't handel it) or is it a heat problem (i.e. get rid of the heat and overclock to higher settings with no image degradation).

bump, anyone?

I've got a V5 that runs hot. I fixed the problem by cutting a 120mm hole in my side panel. I used a fairly loud 120mm JMC fan and cut the voltage back to 7v. The fan is pretty quiet and moves enough fresh air in really bring down my case temp.

An 80mm fan would probably do ok also. Just pay attention to how loud it's rated at.

I have a gainward ti200... I also have a 80mm intake across from my agp card, with a sunon fan on it... I was clocking to 240/490... I then decided to epoxy two 80mm fans to a empty slot plate (those metal thingies for the unused slots) and put that under my video card blowing up into the card's core and ram sinks... Although I am now moving an impressive amount of air onto the card, I could only successfully move up to 240/500... which is basically nothing... I think the best explanation was said by somebody (can't find quote/forgot which forum I heard this) that heat does not become an issue until above 450mhz... and that the real issue is quality of ram.... I think this explanation sums up my experience pretty well... I have seen ti200 cards (pny) that are clocking in the high 400's without any cooling... And I have seen some unlucky visiontek cards that won't pass 450 with all the cooling on god's green earth (read: 3 120mm directed at card...) ... it is kind of a mixture of luck and good cooling... You can try just taking the side off your case and pointing a coupla 80mm's at the card, and see if you get better results... I guess that would probably be the easiest way to see...
