The Freezer 7 Pro, while decent, is no match for the TRUE's far superior cooling performance. Pair the TRUE with a decent fan like the Yate Loon D12SL-12 or the Scythe SFF21F and you'll have a fantastic cooling solution that is also very quiet.
That being said, since the TRUE is a tad on the expensive side, you can also go with the Xigmatek HDT-S1283. But I recommend buying a Thermalright screw bracket for the latter, the default installation kit isn't that great. But that's just about the only gripe I have with it. Cooling performance is on par with the TRUE.
It's worth the upgrade IMO.
