I need a heatsink that can keep an overclocked opty 165 with voltage tweeks well under 50c load. My current Scythe SCNJ heatsink does the job, but when overclocking my opty the pwmic temps get rediculious 56c> in a 70f ambient room. The load temps with my current cooler keeps my cpu under 45c.

Any cpu cooler that can do what my current heatsink can do, but also cool my ram and pwmic would be great. I have a 120mm vantec on the left side of my heatsink blowing towards the back of the case, but since the fan is directly over the pwmic it doesn't cool it because theres no suction created to atleast pull the heat out.

I heard somewhere that xp90c is good as well as the xp120. Someone also recommended the zalmans9500, but its too expensive and probably won't cool the pwmic because of its design, but prove me wrong if you can.

All top quality heatsinks basically will give you the same reading within 1c--3c.
There is NO one best heatsink.
From system to sytem what works for me might not work as well as something else for your system!
Reviews are just that...reviews.
Yet-- How many times have people posted saying they got the latest and greatest supposed Heatsink and its crap?

You see as of this moment its a buyers market.
The possibilities are endliess.

You can get many top quality heatsinks and some of them even look fantastic --9500!!

With that said...you present Scythe Ninja in all the reviews I have ever read took top honors even amongst such heavy weights as the XP120 and the XPcopper and the Big Typhoon as well as the 9500 - NOTE-- at 5v the 9500 kicked ass.

Yet several ideass come to mind that might help you out.

Is the current fan you are using rotating at 40-50rpm? If so great!!
If it is pulling over that you have to deal with the fact that anything over 40--50rpm is redundant and sometimes will actually reduce the effectiveness of your Heatsink.

I see no reason to switch from the Scythe Ninja....but with that said....the Zalman 9500 also does not direct air towards or away from the heatsink.
What both of these Heatsink do is take the heat that the heatpipes draw from the heatsink and then dispose of it.

If you are seriously looking at a XP120 or an XP90c...I would probably get the SI 120...it stands higher and from comparison reviews it cools slightly better than the XP120.

But mind you for your situation you might have to go through several heatsink to find one that gives you the results you want!

Also how is the airflow in your computer?
No dead spots?
Rear fan is your exhaust correct??

Anyways good luck!!

If you were to look inside the case (on the side) you would see the heatsink and my vantec 120mm on the right side of the heatsink. If you're familiar with the p180 case then you'll know what i'm talking about.

The the vantec is blowing through the heatsink (air flow is going front to back) and directly out the back of the case, but the heatsink hovers over the pwmic as well as the fan which is causing a dead spot. With my opty at 1.425v the pwmic gets to 58c tops. The cpu and chipset temp are in the low 40c range. I'm only worried about the pwmic. And yes i believe you when you say my heatsink is one of the better ones, but its only downfall is its ability to cool my pwmic which is really making my computer hot.

I was thinking of going with the zalman 7700 120mm full copper heatsink. I'm worried about it because i'm not sure if its capable of cooling the cpu as well as my current heatsink, but i know for sure it will cool the pwmic just by looking at the design and where it directs air.

I would recommend the XP or SI 120.

I have/had bigger P180 heat issues do to the A8N32, Oc'd Oppy 170, and 1900xt.

I ended up going to extreme measures(do a seach if you want more details) to get the temps and noise levels where I wanted them, but the first thing I did was get an SI 120 to replace the Ninja.

This is really hard to deside. My heatsink cools the cpu extremely well, never has it touched 45c. I found a review of the big typhoon going against my heatsink, and the typhoon good slaultered by 5c in load temps. Remember i'm using a opteron 165, gets a little toasty.

But you know what forget reviews because there so different from one another that its pointless to judge. Anyone using a big typhoon for overclocking a opteron dual core, if so what are your load temps. A good realistic comparsion would be someone with a dfi board and an opteron dual core to get the best results into deciding my decision.

I'm only having problems cooling my pwmic. My cpu load temps (like i said) never touch 45c under prime95 for hours even with a good amount of voltage applied to the cpu, and my chipset is only 43c max running prime95, and 46c max when i'm gaming. Pwmic touches 58c max in prime95, and 52c max when gaming.

But i found a new heatsink that i never heard of, Its called the thermaltake blue orb II. I looks very similar to zalmans 7000, and 7700, but supposivly cools better.http://www.madshrimps.be/articles/ThermaltakeBlueORBII-Liquid3D-9601.jpg

First off the link doesn't work. I figured how to cool my pwmic, I took my extra vantec 80mm and ghetto rigged it on top of my heatsink fan pointing downward at about a 30 degree angle so its blowing over the ram over the pwmic as well as the cpu. My idle temps for my pwmic where 40c, now it idles at 32c with a load of only 36c. My cpu is stock right now though, but what a difference in cooling it made.

I wish my A8N-E's pwm was at 40C. When OC'ing load temps would reach 90C. At stock speeds 70C. I did the ghetto 80mm fan thing, and it only dropped temps by 7C at most. Replaced the mobo with a KN8 SLI and now pwm temps are at 55C at load. That might as well be 0 Kelvin!
