Drop In Waterblock for the Ivy/Sandy Bridge without the Tec Headaches - Page 8

post #71 of 235
I received this unit a couple of days ago and am going to give it the smoke test tonight. I will try it on a test bench first, but given the excellent quality of the workmanship, I have no doubt that it will be a great success. I will stay in touch.

I can't wait for the results .. Something fun might be to run the tec all out if you have the cooling. You can run the actual tec without the controller up to about 17-19v and really get some exciting benches on it The vmax on that block is actually 24v!

Having used phase change and various home-made sub-ambient set-ups in the past, I have gone through the horrors of imperfect insulation often enough that I don't wish to go that route. I rarely keep the same motherboard for much longer than six months as I am sure is the case for many for most of the people here. The only fail-safe way of insulating is IMO complete encapsulation using silicone, supplemented by heating the bottom of the board. God help me if I want to change the processor

What attracted me to your design is the lack of the need for any insulation. In the past, I used a tec waterblock with an Oven Industries controller. Check them out, they make reasonably-priced controllers. However, your design is much more elegant and a heck of a lot simpler, not to mention less costly.

This is the reason I made the block in the first place, for enthusiast such as yourself

Wow this is really exciting. I am eagerly awaiting more results.

Add some black hex bolts as Bass said and this thing will be golden.

Also, waiting on results.

Progress report -- I installed the block yesterday. I am using an Aquacomputer Aquastream XT Ultra pump (love it!) with a stand-alone Koolance 3x120 radiator in an external enclosure. Both the pump and the radiator fans are set to about 60% of maximum voltage values. This maintains a water temperature of approximately 34 degrees.

The block and controller were trivially simple to install. I am using the controller to permit the block to track ambient, about 34 degrees case interior in the balmy New York City summer.

The Sandy Bridge processor is overclocked to 3.9Ghz, an initial value since I have not had a chance to spend a lot of time maximizing the overclock. At idle, in order to maintain the block target temperature, the peltier is running at its minimum of 10% duty cycle!

Running prime95, the core temperature rises from about 40 degrees at idle to the neighborhood of 60 degrees. This requires a duty cycle of a maximum of 35% in order to maintain the target block temperature of 34 degrees. The system can run like this all day.

Mindchill's solution is clearly the best way to implement peltier cooling that I have found if one does not want to bother with below-ambient insulation and all of its attendant inconveniences and risks. I could not be more pleased and eagerly await further developments.

P.S. The build quality is superb. Kudos to Mindchill!

Imagine what this thing could do to a lapped chip...removing the inefficient ihs to give it better access to "direct" cooling.

Pretty amazing invention/innovation.

Wow, nice. I want one... but first, I need a PSU capable of providing the 700w this thing needs, on top of the rest of my rig...
