My 7 systems on local game LAN (see my profile) are using the Thermalright SI-120 coolers and a 50% OC...if they had the Thermalright 120 Ultra's I would expect some sort of CPU temp drop but given what I already have,1/2 of 1C would be the best for me as I already have H2O temps for 1/8th of the average cost.
Anyhow as I have said it is about the -compleat system- and -correct airflow patterns- that keeps the CPU/System temps low.
The same goes with OC's and voltages.
I have no issue even with the same exact build parts reported online with OC except I bother to use PC Power & Cooling PSU's...and meet the same but -without- the voltage boost.
If you really want your "toy" to do it's best then you need to understand and use all the correct parts/information.
@KyleSTL...
It does not matter what those people found.
The "test" they did is not valid in the way they did it and is in my mind nol and voided.
Look at my profile...-look- at my profile.
As I have said it is all about the -complete- system.
The whole world can not agree with me yet my work does what it does and is a fact.
The same concepts the system in my profile uses can be used with newer CPU/MB combo's with like results.
The hardest part is that CoolerMaster no longer makes the same case which was the best cooling ever.
The CMS TO-1 was/is the worlds best case ever with the optional Crossflow Fan.
@ Evilonigir...
I don't lap anything and to add to that I -only- use the "old" white Silicon Grease TIM on customer reinstalls!
Paying for over priced "crap" like AC5 or whatever is like flushing money down the crapper.
People should learn to correctly -clean- the CPU/HS and -correctly- learn how to apply TIM.
Yes I am on the old DFI site now called DIY.
I will not repeat how to clean/use TIM...take your own time to SEARCH my posts on TOM's or online on other sites.
I have been "online" befor what is now called the "internet" and just might know a few things that todays websites (like TOM's) try to to tell people/push products onto.
