the waterblock is only as good as your radiator can dissipate the heat.
Anyone who told you that a new block would improve temps without knowing the rest of your values are jumping the gun here.
Also u listed motherboard values, im guessing, the cpu value listed on your motherboard.
This temp probe is taken directly under your cpu, and has very little reflection on how well the block is holding up.
Can you use a real temp monitor program such as CoreTemp, or RealTemp, and get Tjunct. Temps.
These should have 4 numbers if your cpu is quadcore, and 2 if its a dual.
I dont think your running a hex yet, so you dont require RealTemp GT.
But if your lacking component is your rad, buying better fans, would be a cheaper and greater benefit over a fairly decent cpu block your holding onto.
i have a swifttech dual 120mm rad and i will soon add another single 120mm rad that will go on the back of the case
now fans is my main concern. should i do a push/pull or just a push?
Yes fans will net you a great deal, however the price is noise.
As i said, we needed to know the rest of your eq and values to help you determine what would net you the most gain.
