hello forum.

Zalman cnps7700-cu led, or Corsair A70? right now i am using the A70 air cooler by corsair. im running the 1090t BE overclocked to 3.8Ghz, with 1.50v (my motherboard is horrible with vdroop). at idle my temps are 35C, and underload during intel burn test it reaches no higher than 53c.

I have a chance to get the Zalman cnps7700-cu led cooler for $15. will this cooler be better than the corsair A70? is there some sort of formula to figure it out? any and all input is greatly appreciated. thanks
 
Don't swap the coolers. I doubt that the Zalman would get you any better temps or more overclocking headroom.

I would see if you can tune down your voltage a bit. Seems a bit odd to me that you need 1.5v for a 3.8 oc with that cpu.
 
^tell me about it. in the bios it says 1.5v. when i boot windows and load cpuz, at idle it says 1.46v on the core. underload it drops even more to 1.29v. i think this is why i need so much voltage to gat a stable 3.8Ghz overclock because i cant get my vdroop right. i mean it will boot at 4.2Ghz at a lower voltage, but will fail no matter what the voltage is set to. and if i lower the voltage to anything lower than what i have it at right now my 3.8Ghz clock is not stable. i was hoping that the zalman would at least give me the same perforamnce because it would look alot nicer than the corsair as my motherboard has copper piping and heatsinks. any other suggestions on the cooler or settings for my board to get a Healthier overclock would be great

^yeah thats what i was thinking as well. i suppose ill just stick with the a70, even though the looks arnt as sharp, but does its job. anyone have any recomendation to my motherboard performing better with its vdroop?
 
You probably just got a lemon of an overclocker. I got one too. I have to run my 955 at 1.47v in order to have a 24/7 stable OC. If the chip needs a certain voltage in order to run stable then there is nothing that you can really do to make it more stable with less voltage.
