This was just too amusing to pass on. Having a cooling problem with a 10G fpga board which required some hardcore engineering skillz to solve. Essentially the board has no fan and there is no case resulting in a rather poor airflow and toasty chip. To make it worse there was nothing to rest the fan on thus the below highly engineered solution was taken to the business for approval.
Full purchase order is as follows:
- x1 1 12V fan
- x2 alen keys (one required to be quite long)
- x1 twisty tie
- x1 TAPE! *this is special thermal tape, forget the name but it happy survives 1-500deg C*
The truly novel part of this is invention is the unqiue application of a twist tie to secure the alen key to the heatsink, via the heatsinks own design.
NOTE: technically tape is not required but psychologically, tape is always required.
Dear sir,
ReplyDeleteI'm working on some kernel-bypass code for low latency trading; it uses off-the-shelf NIC card and driver for direct access. I found out that latency is very low, below 5 microseconds, when there are many orders at same time. But when there are much less frequent orders, say one order per second, latency went up 3 times. People told me this is "warm-up" delay and unavoidable; did you have to deal with same issue? Any idea how I can fix this?
Thanks,
PX
