overclocking G400 = excessive heat?

[claw]

If I decide to overclock my G400 32Mb (non-Max), at what point do I need to replace the factory-installed heat sink with a bigger heat sink or a fan? Thanks!

All I did was add a 486 CPU fan to the heatsink already there and I'm running mine at MAX speeds.

Also the Tennmax Mini Lasagna cooler is pretty good. I have my vanila G400 running at 145.8 clock and 194.4 memory without a problem.

the heatsink the standard g400 comes with is probably the best you can get. Go down to radioshack and get a 486 fan and screw it to the heatsink. I used an old pentium fan I had, my g400 has run at 160/200 for 3 or 4 months.

In the moment you experience lockups, the G400 chip is exceeded.

When you start seeing dropouts (white little dots and tearings), your gfx-RAM is maxed out.

To go further you must increase cooling by simply adding one or better two fans on your G400.

For example like this:
