It is quiet annoying that such type of pulse problem has occurred in ThinkPad T510.Since in year 2004 for some of old models of ThinkPad T40,T41,T42,T43 ,X31,X60,R40,600E same problem has occurred. It is actually bug in firmware of your laptop which will cause pulsing. According to their notes on this problem the pulsing actually triggered by the embedded controller when it monitors fan speed. For some models at that time they launched update for embedded controller which solved the issue. You can search Lenovo site for such a update for embedded controller has launched by then for your model also or not.

You have Lenovo ThinkPad T510 right. There is ThinkPad fan controlling utility available over net for download. Try to download it and install it .But be careful it can create problems you may use it at your own risk. This utility monitors CPU Temperature and uses ACPI to control the speed of fan manually. This utility was designed for T41 model but it was working on other models also. The program running as windows service is available for download. If the program crashes system will restart. Such a crash can cause damage to your system. System may give overheating problem and system can cause damage due to this.
