    Default Project Jalapeno

    It can be also used as a DC load but its purpose its to heavily stress CPU coolers.

    Attached you will find a photo of what a colleague of mine (Seafalco, a fellow reviewer at TheLab.gr) has made for me.

    The transistors will not be used in the beginning. Instead we will use 6 TEH100M2R50FE .

    Total estimate max Watts of the 6-resistors equals to 346W, enough to stress every mega-cooler out there.

    In the start I plan to keep things simple (and cheap), so I will use 6 switches to toggle on/off the resistors and one switch for the PSU. Also with the use of a shunt I will measure the current drawn by the resistors and along with the 12V rail I will be able to measure the total watts. Temperature readings will be taken in the center of the plate through a 1mm diameter hole, were the probe will be placed (the hole is 5mm deep).

    Later (when I will have more money to spent ) the switches will be thrown away and in their place I will put some usb controlled relays. Also, with the help of a Labjack and the appropriate module (op-ap amplifier) I will be able to take, in the same time, both current and volt readings. Of course a custom program will be made to control all above and monitor in real time all variables

    The work log of a similar (but much more sophisticated project) can be found here. The man behind this project (Seafalco) is the one that made the plate for my project.

    some more pics as the project is running to its end.

    The development of the control program has already started!

    The surface contact should simulate a real CPU's IHS.
    It's been a hard day's night and I've been working like a dog.

    It's very hard to simulate a real Cpu die. With this tool we will be able to evaluate the performance of heatsinks easily but we we will not be able to say, exactly, how much watts from a real CPU each heatsink could handle.

    Any way you could de-lid an old CPU to provide the contact surface? On old P4 or AMD chip should suffice for that?
    Intel i7-2600k with an XSPC Raystorm water block, 4x4GB Corsair Dominator, SLi Evga-GTX560Ti-448 FTWs, Asrock Extreme4 Gen3, Crucial M4 256GB SSD, Samsung Spinpoint F3 1TB HDD, powered by a Silverstone Strider+ 850 PSU in a Silverstone TJ-07BW case.
    I'm not buying EK GPU blocks ever again. (One GPU killed)

    and the point would be?

    The project is finished. More photos and the full story here.

    Besides heatsinks it can be used as a small PSU tester too

    You have some mad skills. Mechanic, electronic, programming...

    thanks But most of the mechanical staff in this project have been created by a fellow reviewer at TheLab.gr, Seafalco. I only modified the PSU case, the modular PCB and finally assembled all pieces together.

    Seafalco is one of the best mechanics/electronics I have ever met.

    A heatsink tester has a lot to do with mechanics, since the retention module greatly affects performance.

    btw: watch out the conductive Drain pad under the MOSFET.
