I am brewing a simple IPA all grain. I started my mash at 152 degree's. I noticed 30 minutes in that I dropped to 140 degree's. I heated more water and brought the mash back up to 152 degree's. I restarted my hour time table from that point.
Should I notice any side effects?

It sounds like you forgot to pre-heat your mash tun. Before I mash I always heat the strike water about 12-15F higher, dump it in the mash tun and let it settle to strike temp. before doughing in the grain. This takes about 15 min. and will pre-heat the MLT so you don't lose as much temp.
