Thermalright XWB-01 Pressure Drop results

post #1 of 8
Thread Starter 
First I wanted to give special thanks to Gary from Sidewinder for sending me this sample to test. Apparently Thermalright was looking for some feedback on their first block and I got a chance to take a look.

If I hadn't gone water I'd probably be running a TRUE and still be running my old TR HR-05's on the chipsets along with my HR-03 that I had on my 8800. I was a big fan of TR in the HSF segment, so I'm glad they are dipping their feet in water as well, I expect some more good stuff coming from them:clap:

I have several pictures and more details here if you are interested:

And my results:


It actually follows the curve of the EK supreme pretty closely, somewhere in between a fuzion with 5.5mm nozzle and 4.4mm, so it's of the high restriction category, but it appears to be competetive with a stock fuzion, so that's a good sign.

I'm not testing thermal performance yet, but the few other reviews I've looked around at seem to indicate performace would be on par with a stock fuzion. That's pretty good for the price and very good considering this is one of TR's first waterblocks, it's an all metal block, and it comes WITH a backplate!.

It's definately more efficiency focused in production (not much fancy machining going on here, but a well performing block regardless.) Fairly interesting construction, looks like the base is forged with a square insert depression and the actual pins are probably assembled from punched sheetmetal and then soldered into place. You can see punching shear marks around the perimeter of the base indicating a punch type cutout operation of some sort. Not sure the solder has any effect on performance or not, but it's an intersting and very different way of doing things. I always give a thumbs up for something a little different

Anyhow, thought I'd share, I'll work it into my estimator soon.

Did you get a chance to measure the height of the pins?

From the picture, it is hard to determine where it scavenges from (round ports to the scavenge chamber over a square cavity. Do you have a picture with the plate above the pins?

Thanks for the testing Martin...These blocks go in cycles from free flowing to restrictive, looks like they are going back to restrictive again, i'm really surprised Swiftech hasn't brought out a milled base version of the Storm yet for s/775...

For more flow you want the curves lower, less PSI for every GPM.

Some restriction is a trade off for better thermal performance, but alot of times restriction is just inefficiency in the design. Sharp entrances and such have no benefit to thermal performance, they simply mean more restriction.

Pressure drop is just one of the two measures of performance, the other is thermal performance relative to flow rate.

Preferrably youd have low pressure drop and high thermal performance, but usually there is some trades back and forth.

Can't wait until you start thermal testing. You will be publishing just about the first comparison of temperature differential vs. heat dissapated and flow rate. All of the others usually give 4 or so heat dissapated numbers, all at unspecific levels (idle, load, OC idle OC load) and virtually never vary the flow. It will be quite interesting to see how the Thermalright, nozzled Fuzion, and EK Supreme respond to different flow rates.

Keep up the good work!!!
