Darkbreeze :
There is no point in upgrading from one 120mm cooler to another one. There will not be a significant thermal difference. 1°C difference is irrelevant in the scheme of things. Unless you can get an 8-10°C difference in temps, and even then, only if you are currently not able to keep your CPU temps within the thermal specifications, changing coolers is probably a waste of time and money.
Unless your case supports a 240 or 280mm cooler I would not bother unless there is an actual PROBLEM with your current cooler. You'd probably be better off upgrading your case fans than your cooler, or depending on where your cooler is mounted, moving it to a different location if it's currently not cooling as well as it should be. Your Deepcool 120 is ok, but it doesn't even cool as good as a decent 140mm air cooler, and neither do ANY single fan 120mm water coolers.
If you want to upgrade your cooling I'd focus on a very good air cooler or a larger water cooler.
What makes you think you even NEED a better cooler? What are your system specs? Are you overclocking? What is your case model and how many fans are installed. What is the orientation, intake or exhaust, of each installed fan? These are the things that matter, not which model of cooler you are using.

Temperatures:
I always believe that aisuite temps are absolutely rubbish with -10c & +10c fake temps comparing with other apps like hwmonitor, asus intel extreme tuning utility
idle - browsing chrome with usually 5 to 7 tabs opened
Ai Suite (POWER SAVING) :19-22c
Ai Suite (PERFORMANCE) : 20-24c
asus intel extreme tuning utility (POWER SAVING): 30-32max.
asus intel extreme tuning utility (PERFORMANCE): 33-35c and sometimes 38 -50c INCONSISTENTLY keeps jumping in temps

wwe : When i use GPU BOOST to max voltage n freq from aisuite the temps in Aisuite goes to 97c while extreme tuning utility displays 83-86c around. so this makes me go mad when temps goes like 90+
I never thought i would get 60+ temperature while gaming but i have realized this might be a poor AIO or AISuite auto OC or whatever it does behind makes the temps raise in performance mode
core feq: 4.2 or 4.3Ghz max
core voltage : 1.35V and sometimes 1.4V . i dont totally understand this aisuite which automatically puts cpu into risk with over voltage and its auto basic OC by itself.
i usually love to keep my things upgraded and in near future if i have to upgrade my AIO, which one i better consider buying and which cooler standards i should not consider?
