I have a CL Voodoo2 12MB in my system (AMD K6-2 300, FIC VA-503+, 64MB PC-100, STB Nitro 3D, and WD 6.4GB HD). I am getting unexplained errors and lock ups in all programs when the system has been running about 1.5 hrs and continue unless I shut it off for about 45min. I think I might have a cooling problem. If so are there any good cooling fans for the CL Voodoo2 card ISA or PCI. I also would like to know if I need to up my power supply, its only a 140 watts. Any suggestion or solutions would be helpful. These problems did not occure untill after I installed the Voodoo2 card.
