The Senfu water-cooling system
The Senfu watercooler is manufactured by Senfu International in Taiwan. This system consist of : aluminium waterjacket, single or dualfan radiator, fastening system, hoses,peltier, insulation and a pump. This items can be bought together or separately.
Since there have been loads of Senfu reviews around I will not go on and on telling you detailed about this system, here is the short version with a little evaluation , lots of pics, and how it performed with our verified Celeron [email protected]
The First impression
When I first got my hands on the Senfu system, I was very pleased with what I saw. It seemed like a good constructed watercooler that had everything you needed to get started. After some more examination I noticed a few things that should have been different. The pump is rather useless, it cannot pump any higher than 1 feet, so everything has to be nearly leveled to get a good water flow. In this test I have used another pump. It's a lot better and runs on 12V. I was very impressed with the dualfan radiator. I first tested it in my own watercooler and it performed very good. It has long inner tubing and the two fans really help cooling the water - but it's a bit noisy. Also it uses very small inner diameter of the tubing. Actually so small I had some problems with getting larger hoses to fit. This also causes a bad waterflow.
Senfu deliver three different radiators :one small one with single fan and two bigger ones with dual fans. The difference beetween the dualmodels is the strenght of the fans. These radiators are really good as soon as :

Senfus waterpump is actually pumping almost as much water as the Eheim pump - that is until you put on the adapter for the tiny hoses the Senfu kit comes with. As soon the pump get some pressure to work against the flowrate decreases dramatically and the noise increases to a unpleasant level.
The waterjacket is very tiny, first I thought that this could never perform any good, but I quickly changed my mind when I got it tested. It has good potential and it gets rid of the heat very good. I also noticed that it had a very coarse surface. So sanding the jacket is going to have a big impact. This test shows the unsanded version of the Senfu.

The Senfu has fastening systems for all the popular CPUs and they can easily be changed. But the fastening system for the Socket370 CPUs should have been improved, because if you are to use a peltier with coldplate it builds up to much for the fasteners. It comes with a string that should be used in these cases, but I found it very unpleasant to have the waterjacket attached so loosely to the CPU.

On to the testing
In this test we used our verified Celeron [email protected] with Asus slotket. With a single 53W peltier element with aluminium coldplate and water at exactly room temperature I could get it 100% stable at 640Mhz. Now that is a very good result. I could easily reach 682Mhz ( 5,5x124 ) with heavily cooling of the water. Remember also that the waterjacket has not been sanded.

I have to admit that I got more and more respect for the Senfu system as I tested it, it has great potential and is especially great for beginners in water-cooling. Also the waterjackets small size and light weight is positive. It also have some negative factors like small hose inner diameter and that the waterjacket probably needs some sanding.So my conclusion is that its a great system for beginners, but it won't stick out with the more hardcore guys. BUT if this kit came with bigger bore in the waterjacket/radiator and used bigger waterlines we think Senfu would have had a killer system !
Thanks to Senfu International for sending us the watercooler.
