There have been many threads on how to help owners with 7000//7700 series coolers by Zalman... I am going to list a few methods here (ones I have done myself):

#1: Case Fan Direction:

This one is the easiest... Props to evaseeker for this one...

Well, normally, the zalman fan blows air ALL around it... thus blowing hot air down into the sink with a normal case fan config (front intake, rear exaust)... What evaseeker found was that it was better to have the rear fans blowing in... that way, the zalman gets cool air, and blows that down onto the heatsink, making cooling performance better... I have pictures showing what I mean:

This is a normal case airflow layout:

With the zalman, that won't work out as well.. The rear fans will exaust hot air, but not as much as needed, and the zalman's fan will be sucking in hot air. So this is ideal:

Also, if you have a BTX case configuration, it is much more optimal than an ATX config, as the CPU is on the bottom, and heat rises. So instead of having front intakes, you can a standard back-to-front airflow config.


#2: Zalman Fan Replacement:

Probably the most common zalman mod... The stock zalman fan is horribly slow... If you arent TOO much of a silence freak, get a new fan... it will benefit highly (Magick Man uses/used a 120mm fan with a spacer, and slips/slipped it over the actual sink)... With minor modding, you can get a 92mm fan, gut it leaving a few stubs, and then drilling 1/16" holes in the stubs... the screws from the stock zalman fan will self tap... Props to Navig for giving me a pretty in-depth 'tutorial' on this (shown here)...

my first fan replacement, a Panaflo 92mm High-Speed with RPM reading [FBA09A12H](56.8CFM): http://community.webshots.com/photo/335682843/281611839DNQfIs

I didn't feel that the panaflo was enough, so I went a little beefier:

Delta 3-blade 92mm High-speed [EFB series](~80CFM... YIKES)... Same mounting as the Panaflo:

#3: Base Lapping:


Thx to EWBatOVAclockin for this one:

you might think the zalman base is flat... from what I've seen, it was far from it..

see what I mean?:http://community.webshots.com/photo/335682843/314475680ZLFSNO

lapped it up to 2000Grit (with a finish of printer paper), and its a charm now... look at the difference:

and the moment of truth:
http://community.webshots.com/photo/339739088/339739088fYaGwN

I lowered my temps around 5 degrees after adding the delta and lapping my base (using ceramique) as compared to my unlapped base and the panaflo (using AS5)...

If you have any questions, feel free to PM, E~Mail or AIM me.

Vere nice indeed solid. I did try the case fans at the back but so minimal differences. But once I get my new msi diamond I'm going to try that again AND redo my lapping on my sink. I wasn't too satified with my first one, so I'ma go for another round :cool: But a good read for all 7000/7700 owners.

I really don't see what else could be added. Only other thing I've done is added a intake fan on my acrylic window that almost matches the delta cfm. It does provide it with nice fresh air. I also made a custom duct because of the zalman's circle shape, I got pics of you want so just say it and I'll throw them on here. It did lower the case temps and maybe 1c on the cpu. But again I will try all the stuff as an "experimentation" whenever I get my new board and report back, so we can maybe make a sticky out of this :santa:

PEACE
 
ninja ^^

haha, thx subtotal and EWB...

if you have any comments, please post here...

and, sure EWB, post the pics here if you want... this is a good thread to show-off 7000//7700 mods ^^
 
Alright I will be sure to put them up but as of right now I fried my moniter.........( I tried to spray paint it black :rolleyes: ) So I have no moniter temporarily. But when I get that back I will be sure to put them up here.

PEACE

when I first read that, thought you like overvolted your monitor or something...

:D
 
Thanks for ideas.
Just now I've got Zalman clone, which utilizes 80mm fan, which I'm going to replace with modded AC fan 3 TC. We'll see how it's going to work.

I also had not that bad results, when one of rear fans (got 2x80mm fan at rear and one on top) was blowing in and one out.
Direct ducting air intake to centre of heatsink might help too, but I haven't tried it so far.

Has anyone tried mounting fan on Zalman (clone) that would actually suck air?

Unless the fan blows away from the stationary hub (which most fans don't), you're stuck making a custom mount to hold the fan... I could think of a way, but it would be pretty hard unless you have access to solder/weld (or if you're inclined enough to drill holes and hope it supports) a custom bracket to the sides of the heatsink (so it has like, a metal square, and then 4 holes for the fan to mount to)

Thanks for advices. I have tools and experience in making such stuff (home made WBs, 2 P4 coolers on graphics card etc).
I'm just more curious if that's potentially good or dumb idea. If it's bad, I'll end with Arctic fan 3 TC. It's got pretty weird mounting too, but it will push air rather than suck.
 
I wouldn't like to have a fan suck on the 7000Cu, as it probably won't have as much pressure taking air off the fins towards the bottom of the sink... Whereas blowing will take air from the whole sink down, but blow it everywhere

Incidently, that's how I accidently applied my AS5 installing my Zalman, to great results. I had one solid blob, but it was stuck to the tip of the applicator so I had to wrestle it off, and it looked like that there.

Yup, thats right. I don't like having a strand of extra TIM hanging off the main blob and then going over other components, so I kind of rub it off on other areas of the CPU
 
Very nice. I've been thinking of throwing one of my 120mm sanyo denkis on and then putting a shroud around the edge. That way air is pulled from the bottom and forced out the top. I'm not sure if it will be better or worse, but I figure its worth a try.

You're Sanyo's pull away from the hub? Most fans blow into the hub, and not away.

@Ven0m: Yeah, I figured a mirror finish would always be better. Think about it:

A flat surface without mirror finish is FLAT, but has scratches which = less contact with the CPU. It contacts the CPU, but has scratches.

A flat surface WITh a mirror finish must be flat AND smooth, which = more contact with the CPU.
 
wow, this is so great. You must put a lot of effort making this tutorial post !!
Well done !! Bump up !
