Summary: Zalman proves once again that they know how to engineer things and refine them over time. The WB5 is worthy of just about any high end installation. Cools as well as a dtek fuzion, costs less, and has a much less complex mounting approach.
Pros: Terrific value, super high quality construction, great mounting mechanism especially on AM2, and most importantly, cools as well as water blocks costing twice as much
Summary: If you are debating what part to buy I highly recommend the guide in the water cooling section over at Extreme Overclocking. It answers tons of questions and has performance reviews on everything.
Pros: Zalman stands behind their products like no other. I purchased the WB3 a long time ago, then 9 months later upgraded to a AM2 (non-compatible w/ WB3). I searched their website for a new clip and discovered a typo in the FAQ that said the WB3 is compatible with AM2. I pointed this out to the Zalma...
Cons: Zalman uses anodized Aluminum in all of their waterblocks. Even with the anodizing this metal will still corrode when other metals are used in the loop. You can partially prevent this by increasing the ratio of additive/distilled water. But of course a higher additive ratio results in decreased t...
Summary: I'm not an overclocker. This is for a server board, and it performs extremely well. My CPU is only several degress Centigrade above ambient, and I am only using a single 120mm radiator.
Pros: Installation was easy. Barbed fittings and clamps make it easy to match to any tubing (versus compression fittings). You do have to remove the motherboard, as with most coolers, but the instructions give plenty of detail.
Cons: Hold down clip alignment a little confusing for my 775-series Conroe, but figured it out (sort of an over/under cross-aligning of the clips).
Summary: I ordered this as a replacement for the WB4 block that came with my zalman reservator 1 v2. I had managed to heat the WB4 block up enough that it lost the seal between the copper and plastic parts, which then leaked water inside my case.
Pros: All metal construction. Fits well on my asrock x48 mobo. Keeps my Q9550 CPU very cool.
Summary: If you're looking for an am2+ water block, this one is a definite keeper. Included all the hardware I needed and all nozzles came tight upon delivery. Highly recommended.
Pros: This water block is amazing. Congrats to Zalman on being the first company to release a decent water block for am2+ processors. This keeps my phenom 9950 under 120 degrees all the time.
Cons: None really, it does have one tiny little petty design flaw. In the product manual it tells you to install the block with the inlet nozzle above the outlet nozzle, but on my mobo you can only install the block with the nozzles side by side. I don't know if it makes a difference, it still keeps my...
Summary: THE INLET SHOULD BE THE CENTER BARB,OUTLET SHOULD BE THE TOP.
Pros: Excellant fit,High quality. USE THE SCREW DOWN 775 HARDWARE AND FITS GREAT//// THE SPRING LATCH IS FOR AMD PLATFORM! VISIT ZALMAN,WATCH INSTALL MOVIE WILL SHOW HOW TO INSTALL AND THE RIGHT HARDWARE.
Summary: From what I've seen, due to same configuration on the XFX MB-N780-ISH9 MB this problem would also most likely exist. So if you have one of these 2 MB's you might want to look into a different CPU water cooler.
Pros: I'm sure it's a great working product because I've been running a ZALMAN ZM - Reserator1 V2 Water Cooling System on my PC for 2 years with no problems.
Cons: When I tried to install it onto the EVGA nForce 780i SLI MB, I couldn't latch the clip which goes over the water cooler because of the 4 black boxes next to the CPU socket.
