Conclusion
Performance
XSPC designed a stellar product in the Razor GTX680 water block. Not only did the block drop card temperatures by over 50C under load, but allows the test bench EVGA GTX 670 FTW card to realize a performance gain of over 10% in games. And this performance gain only increased card temperatures by a mere 5C under load.
Pricing
As of August 14, the XSPC Razor GTX680 water block was available at FrozenCPU.com for $99.99. The board was also available from other retailers such as Sidewinder Computers for $119.99.
Conclusion
Before continuing with our final thoughts on this water block, we would like to take this opportunity to give our friends at XSPC a hearty “Thank You” for giving us the opportunity and pleasure of reviewing the Razor GTX680 water block. XSPC combined the design of their initial GTX680 block and melded it with their full cover card design, resulting in a phenomenal product. The Razor GTX680 card is easy to install and use with its versatile multi-port connector allowing for unprecedented flexibility when hooking into a system's water loop. Its sleek looks, a black and copper combination, are heightened with the added LEDs giving the block and video card a pleasing edge-lit effect. Its performance numbers speak for themselves with load temps over 30C less than measured temps when using the stock air-based cooler.
Strengths
- Full front card coverage
- Multi-port connector -> a full seven inlet/outlet ports
- Edge-lit LED lighting effects
- Heat dissipation capabilities
- Quality workmanship and design
Weaknesses
- Lack of packaged back plate
Is there a reason we you only
Is there a reason we you only show the temp over ambient vs actual temp? Most households would have ambient temps between 22-26. I just think actual temp would have been easier for an idiot like me to comprehend.
Of course, there is ambient
Of course, there is ambient temp within the case, which is probably what should be used… but still confusing. Just give me temps! TEMPS!!!
We report delta temps instead
We report delta temps instead of actual temps to allow you to calculate what your temps would be based on your house or office ambient. The delta temps are the card gpu temps minus ambient temperature measured at the time of testing. We moved to reporting delta temps rather than measured temps based on user feedback from previous cooler reviews.
For example, typically my home office temp ambient is between 26-27C. For stock temps with the ambient at 26C, the GPU temp should idle at 28C and go up to 47C under load temps. If the ambient were 21C, the idle temp should be 23C and load at 42C.
add the numbers in the graphs
add the numbers in the graphs to your ambient. There’s your temp.
your ambient: 22
card delta: 10
22 + 10 = 32 degrees
math = gud
Yea, I just didn’t realize
Yea, I just didn’t realize what I was looking at initially. Many times I elect to just jump straight to the graphs, and they didn’t state anywhere that they were based on ambient… had to actually read. Knowledge is power!
Finding it hard to justify
Finding it hard to justify $99 for this waterblock.
The 10% overclock is not unrealistic for an air cooler, especially an aftermarket cooler.
Aftermarket coolers are typically very quiet.
Real-world usage will not push a 6xx/7xx series card with an aftermarket cooler beyond 70C, perfectly acceptable ultimate/maximum-use temperature.
Waterblocks are typically made for reference model designs, which fail to match the benefits of aftermarket designs.
If you can find an aftermarket model for the same/near the same price as a reference model, why bother with watercooling?
Keep in mind that the EVGA
Keep in mind that the EVGA GTX 670 FTW card used for the review came overclocked from the factory, so a 10% overclock with that card equates to a more than 20% overclock on a vanilla GTX 670. On a non-factory o/c'd card, the boost clock speed for the GPU typically hits 980MHz.
The choice between using an aftermarket cooler vs a water cooler is a long running debate that really has no right answer. I've been water cooling my rigs for a long time, and prefer that to pure air cooling mainly because of the fan noise associated with air coolers if you want to push the performance limits. It really comes down to the preference of the inidividual enthusiast…
Steel touching copper with a
Steel touching copper with a fluid running between them. I’ve had some issues with this before.
As long as your coolant has
As long as your coolant has some type of corrosion inhibiter in it (which most good coolant's should have), you should not run into any cross-metal type problems like galvanic corrosion…
The coolant is supposed to be
The coolant is supposed to be “non conductive”, so electrolytic/galvanic corrosion is a non-issue. Especially since the steel used is stainless and the copper is very pure and the lifespan of the cooler is much much shorter than it would take for the electrolysis to damage it so badly as to cause a malfunction. Would it be Aluminium instead of steel, it would “pee” in a few weeks.
Most of the good pumps used have a stainless steel part touching the coolant and there are no horror stories floating around.
Mild steel is a completely different story, that much is true.
Morry – i love your reviews,
Morry – i love your reviews, just one question: do things work when you put them back together? jk. keep up the awesome work!
Thanks. And yes, in most
Thanks. And yes, in most cases they do work after putting them back together. There was one time in the recent past were teh take apart result in disaster – but we won't discuss the H80i dissasembly here…
I like to see both because
I like to see both because what many heatsink reviews fail to show is the cooling performance curve with ambient temperature, eg CPU temperature will not scale linearly with ambient temperature, it tapers off slightly as ambient gets higher.
so temperature over ambient may not be the best indicator if you have some test done in a hot environment, where a 5 degree rise in ambient may only cause a 3-4 degree increase in CPU or GPU temperature.
I notice this with my current air cooler.
Good point. I will continue
Good point. I will continue to report in deltas in future cooling reviews but will include ambient temperature at the time of testing as an additional data point either in the graphs or test description.
Typically, my office ambient runs between 25-27C which is most likely typical or a bit hotter than most homes / home offices.
Thanks for the feedback…
