So i had a zalman wb4 on my amd 5200 and my temps were higher than my air cooler! on air i was around 44c under load. with this water block i was 58c under load! well didn't like that so i went back to my air cooler and as i took the block off i noticed that the base of the block that is in contact with the cpu does NOT cover the whole surface of the cpu!!!? is that normal? is it just a bad design :shrug: anyways has anyone else noticed this.

to further explain what i saw, the block is round the cpu is square.
(remember that fun game when you were a baby where you put the round shape in the round hole and it wont fit into anything else, i think these guys epic failed that game.) anyway round block just barley covers the top of the cpu, but the corners of the cpu were left exposed to air.... seem right?

Lets talk about the rest of your loop and how you set it up. Only the 1.5 cm center of the chip I think generates heat. I just dunno, it's an AMD and an odd block. Could be a pump or rad issue too.

Looked it up, WOW thats OLD, it might be unable to keep up with any modern chip......

I don't like the look of the big blocky towers on that thing. Most of the Water blocks I have looked at have less restrictive looking ways of dissipating heat, like pyramids, or non restrictive grooves. And I have to ask. Did you have the water going in the center intake of the block or the side one?

this was with everything brand new.rad and pump were good, flowindicator spinning real good. rest of the loop. went to the cpu first then to the vid card an 8800gts (it cooled that thing REAL good 30-40c drop!) then back out to the reserator, (pump resivor and pump all in one thing) passive cooling yes, but i expected it to do better on the cpu. was real impressed with the gpu. ya it is kind of old. but only the center of the chip makes the heat? well ok it making more sense now, if the edges dont make any at all.

i did have the inlet going into the center :) it does look like there is no "flow" built into it, maybe that is this blocks issue. what block do you guys use for an amd?

The only thing i can suggest is a new block, the best zalman can do is try match high end air cooling passively.

There are plenty of blocks here to choose from all ranging in price.

Something else id worry about is the pump, the reserator pumps have been known to be very weak and sometimes die.
