my frien soemthing is not right with your loop a double rad and a good block e.g ek supreme should be fine for the job.
my i7 can reach 3.8ghz with only 1.25vcore you won't need a quad rad or a tripleI would run 2x doubles one for your GFX one for your CPU
my cores always differ, the thermal paste has been perfectly applied and the results are always the same aparently its a common fault, therfore I only take notice of the top cores.
managed to tweak it to 4.1ghz same voltage...
max temp under load....
hmm try measuring using core temp this is accurate, I'm running at 1.43v on my core and getting 48c sounds like your temp monitor is in accurate.
prety sure them monitors are infact innacurate by around 9C maybe soemone else can clarify, but core temp is correct...nice rig though
what kind of volts you runnign I'm amazed you can get them temps, how you measuring them? I'm running a fesser exchanger quad rad with d-tek fusion v2 and only managing 48c @4ghz!!!!
What programs measuring your temps???
not to take the eye off your rig but this is mine and my temps are...
