So my MB Pro Core Duo from 2006 is running pretty sluggish as of late. I know its been a while and most likely I need a new one but I'm plan to hold out a bit longer. iStat is showing my right fan is out (its been out for a long time). I've been using a program to run the left one at max to keep from getting too hot. If I get a new fan should this help it to run better? I have Onyx installed and have done a few other things that I think should help. I have 4.8 gigs available in free space. Other stats 2 gigs of ram. I see some temps in the 130's on iStat. What else can I do to reduce sluggishness? Any recommendations would be greatly appreciated. Thanks.
