A common problem with the clone e3d v5 and v6 is the fans supplied are not acceptable.
You need at least 5cfm of air on that little 30mm fan to make the heat brake do its job. Get a high RPM BB 30mm fan on that..... here is the one I put on and it cools great:

I use it on this fan shroud assembly that I printed with ABS for better heat resistance:

The setup needed a silicone sock tho as it was cooling my hotend temp too much. [www.thingiverse.com]
if you really want to monitor the temp tho maybe better than using the Ramps maybe get an el-cheapo temp probe.
I think your unlikely to worry about this after you work out the issue and correct it.
