2 out of 5 eggs Good chip, fan is too loud for HTPC use 12/17/2013

This review is from: GIGABYTE GeForce GT 640 GV-N640D5-1GL 1GB 64-Bit GDDR5 PCI Express 2.0 HDCP Ready Low Profile Video Card


I needed to upgrade my existing discrete HTPC card for a bit more ability with the latest codecs. This chip looks to be a great use for that.

Great that we finally have some decent low profile cards to choose from.

Nice that it's a true single slot cooler, but that also leads to the Cons below.


The cooler fan is much too loud for HTPC use. Even when under moderate load it's very audible. Even the wife notices which is bad.

I've tried a number of the software tools to quiet the fan and they do work to an extent at the high end, but then make the low RPM speed even higher than default. So you end up with less noise on the high end and more noise on the low end.

In the end this card is not going to stay in this machine. I may try and pull a dual fan setup from an older nVidia low profile card and replace this one. At least the noise from that fan is tolerable.
