Voodoo3 2000 And Heat In A Desktop Case... Bad Combo?

Mr. Paulson informed me in another thread about the lifetime warranty on the V3 2K cards. That was great because mine was locking up during 3D games. 3dfx allowed me to RMA it on August 29th.

The card had worked OK on my AX6BC in my full tower case for about a year without any trouble. After moving it to a P3B-F in an Enlight EN-7200 case. The card locked with or without a fan on it. The replacement that 3dfx sent out would lock if it didn't have a fan. I used a Nidec GAMMA 28 Ball Bearing Blower on it and it worked fine. So I left the blower on it's been working great for the last month.

This last weekend we installed a Lego construction game on Friday night. It was used a while and the PC was left on all night. It's on 24/7 anyway. In the morning there were "artifacts" by the cursor. I had my son reboot and there were many vertical line type artifacts in the Windows splash screen. At the Windows desktop the icons were small and opaque with very dark background.

I replaced the video card with a V3 3000 and it worked fine. The tech fellow at 3dfx said that it must be heat related. I told him about the blower. He took down all the info I could give him. He even talked me into installing the bogus card in my own PC. Same artifacts etc. He told me that I should have had the refresh rate on the other PC set to "adapter default". I had been running it at either 60Hz or Optimal. It's a Seiko 14" and that's the best it can do at 600x800 true color. The tech. was searching through Price Watch trying to find me a new monitor while I installed the card in my own PC :)

The guy was a riot. He said there are about 30 technicians there, but only 17 were on duty at the time. He said the Que. was about 30 people deep. And here he was spending 25 minutes on my call! Well, I can see his point. He said the chances of having 2 cards go bad like that was rare. That there must be too much heat in there or the mobo may be at fault.

BTW, while talking he mentioned that he didn't care for the 15GB IBM HDDs that I said were in short supply. While we talked, he located one on Pricewatch in stock for $105. Like I said, he was a nice guy, but maybe not quite accurate. He also mentioned that he builds high end gaming machines in the $5,000 price range! :Q

So, who thinks that case is too hot? The monitor in the BIOS says the mobo temp. is at 87 degrees F and the 400Mhz Celeron is at 125 degrees F. The tech said I ought to carve vent holes in the top of the (3 month old) case! Is it the case? 9 year old Seiko monitor? 3 month old Asus P3B-F mobo? V3 2000 AGP inherently hot or poorly designed? What more can I do than having that blower on the heat sink? Any other suggestions?

I recently acquire a V3 3k and man was it hot! I strap on a fan and it wasn't as good either. It got really hot being the only card and system is opened.

i have my voodoo3 2000 PCI 143@175 and it's just warm to the touch. i put a 486 heatsink fan on the heatsink, and i have a dell microtower, so there isn't alot of ventilation, so i added 2 80mm 34.4cfm fans, one intake blowing on the voodoo, and one exhaust. works quite well

I have a Voodoo3 3K too and noticed it was very hot. I pulled it once while rearranging it and burned myself on the heatsink about five minutes after I let it cool. I tried to keep it away from my sound card as possible but I'm wondering if I should get a fan as well

It's weird, I have the newer version, SGRAM, do you guy have the SG or the SD RAM version ? Definite think you should get a fan!

the Voodoo 3 is by default, one HOT SOB. however it stands up to the heat very well (can't be said about that many components).

for me, I dissipate this heat with a huge 120mm fan blowing in from a whole in the side of a case. this heat is then blown out the case through my blowhole in the top. the heat might go through a few other components, but it's MUCH better then leaving it sitting there getting hotter and hotter.

so, be sure that you have a decent amount of circulation around the video card, that will carry heat out of the case eventually (as long as there's air going in and out, it helps).

I've been wanting to put a socket 7 fan on the Voodoo 3 for additional cooling (so I could overclock it higher then the RAM default of 183 without overheating which is what did when I ran it at 195mhz plus (190 worked absolutely FINE!).

your case temp looks looks pretty good. I think you can rule it out as the problem (I personally don't think it is).

BTW, my temps currently are (according to my mobo monitor): CPU - 115F, Case - 85F. this is with a K6-2 400@ 420, Voodoo 3 2k AGP overclocked to 183mhz, and a fair amount of other devices as well.

my K6-2 runs REALLY hot. if I have a few mm not being in contact with my heatsink, I get an instant freeze in windows startup. I need a better heatsink/fan for that..

Mine doesn't seem to have a problem with heat. It'll @ 175mhz (talking about v3-2k here) without a fan and in a stuffy case. If I add a little 50mm fan on the heatsink, 183MHz no problem. Been running it overclocked since I got it... in April 1999 :Q :Q damn i need to upgrade the video card...funny thing is, it's running everything fine. I later built a system for someone and used a V3-2k and it wouldn't clock higher than 155MHz and I believe it was heat related...maybe the original boards were just better?

I only ran my 183 with cooling, just to be safe. I probably could have without the 120 mm fan blowing on it (it's actually blowing on the top 2 cards, and above the Voodoo 3 towards the chipset). my reason for not trying is one of being as safe as possible.

I only tried 200mhz to see if it could be done. windows ran fine with it, however 3d games wouldn't run, becuase it was already running too hot (I know it's heat related, becuase when at 199 it would start showing artifacts int he middle of the 3D app, and then hard lock, a sign of too much heat!)

if I put a fan on the core, I bet I could get 200mhz no problem, but I won't try, becuase I'm really not stressing this card at all when it's at 183mhz becuase the core handles 200 fine (with appropriate cooling), and the RAM is rated at 5.5 nanoseconds (therefor I should get minimal reduction in lifetime in components that aren't guaranteed at higher mhz, such as the SDRAM, which is my biggest concern).

Well, I ain't overclocking the video or even the CPU. You guys think it's just a coincidence that this second one puked? Do they repair the cards that get sent to them and ship them off as replacements?

I asked if I could or should bump up to another card, but he just kept hammering the heat issue. Look, Enlight ought to know how to build a case. I'm not overclocking anything and the only game to stress it this last month was that "Lego Creator" thing. We haven't even played much, if any, UT to speak of.

The S540 PCI doesn't seem to be suffering in the same machine. I have no fan on it at all. If the next card 3dfx sends out craps out will they RMA it too? What the hell is my responsibility in all this? It's all new, name brand stuff in there except for the monitor. Could that be the problem? Any thoughts are appreciated. I obviously have to take some action here...

well I personally don't think heat is an issue. my case isn't hot at all (though my CPU is a hot SOB, I could cool it better with a good heatsink/fan combo, and my whole case temp would probably drop ~5C), and I'm running overclocked, stable as hell.
