ehhhh...... i've read a few reviews bout the thermaltake heatpipe. from what ive read its basically zalmans design that thermaltake has just added some stuff to. the review i read said that the extra blower on it didnt do anything much as far as performance (maybe cooled it an extra degree) and that it was kinda loud. and as for the three different fan speed settings there wasnt but maybe a degrees difference between each setting. i dont know, i may end up getting it. the reviewer said it performed well, but the extra blower fan just more or less made it loud and added minimal performance and the fan speed setting didnt do much either. but, if it fits and the zalman wont...... then i may go with it.
