Necroing this old post since I tried to do something while i dug my 2010mbp out of storage. In additional to the throttling fans were also going full-blare.
I tried NoBatteryNoProblem but I couldn't really tell if it worked or not, it had no effect on fans. I was using 10.8, but in newer OS you might need to additionally remove IOPlatformKext and/or write some other MSR values
although memory leak doesn't happen anymore, but the cpu somehow still capped at 1.5 Ghz, BD_PROCHOT option does not effect on my bad battery @christophe-duc plz help me I did notice that Bi-Direct...

(note please don't blindly copy instructions there, MSR 0x199 might not exist for your model computer).
Anyone know if there's a way to get the fans to shut up? I actually suspect not, because I saw that fans were going full throttle even during sleep and even from the initial boot before OS loaded; so I suspect it's something at the SMC layer which is causing fans to go full throttle when battery sensor is absent. One thing I did not try was forcing fan to a specific RPM using the SMC key (note this is _not_ setting the min RPM, this is forcing the RPM directly via the same mechanism used for e.g. AHT). You'd probably need to have some other daemon to match that against CPU temperature though.
