why would you need these? I thought that the Pi doesn't get that hot to warrant having heat sinks?

Under normal use that may be the case. However, in my particular case, I have the board in a Pimoroni Pibow Ninja case which doesn't have the most airflow. Coupled with that is the fact I have my Pi overclocked to the highest setting (full 1ghz). These things all taken together plus watching full HD output video causes things to heat up considerably. Put another way, need them or not, it's such a small investment for a good deal of peace of mind why WOULDN'T you get them?

You don't need them at all for normal use; overclocking/overvolting would benefit from the heatsinks to maintain the longevity of the chips. Small overclocks (up to 1 GHz) generally won't require them in a normal ambient room temperature.

You really don't need them. I just bought them because I wanted to buy them. They do keep the chips slightly cooler which will help prolong their life. I have left the Pi on for months without a problems.

It helps if you're doing any significant overclocking. I run mine at 1.1GHz and some high voltage level that I don't remember offhand, and without heatsinks I couldn't do that with stability. Even at lower clock speeds, the 10-20 celsius difference can make you "feel" better, although I don't know how much of a realistic difference it will make in terms of functionality and useful lifetime.

Over clocking as well as putting your Pi into a case will increase the temperature that the chips operate at and extreme temperatures will cause stability issues.http://stevenhickson.blogspot.ch/2013/04/attaching-heat-sinks-to-raspberry-pi.html

I would think that the heat produced by a faster drive wouldn't help. This gear has no fan (although it has a place for one - and a molex connector)

The heat sinks are not much bigger than the ram itself.On every installation of these I have made, the heat sink does not overlap the socket and does not add much to the height.

I run 4 of them right now with one slot empty in between them and it will run without a fan. However, these seem to dip to 1.4 GHash/s after awhile (even with a fan). Could be my USB hub. Seems fine if restarted.

There is heat compound fixed to the heat sink so you should not need anything else.

It would help but it's not necessary unless you overclock a lot. I don't overclock and my cpu never heats too much.

The purpose of this heat sink is to provide a quiet PC. This is a fan-less one. Besides, you should not turn on turbo mode in the BIOS or the CPU will be overheat.

I agree with the other...you dont need any additional because there is already some there. If you messed that up, then scrape it all off and apply a small pea size on the middle of the heat sink or CPU and gently put the cooler back on and lock into place.

The system one you can can just tape to your power supply or hard drive/SSD. The graphics sensor and CPU sensor can usually fit in the fins of the heatsink. The sensor wires can bend so I usually put the end of the lead into the middle of the heatsink, under the fan, then tape it in place (they give you heat resistant tape strips). Do not be tempted to put it between the GPU/CPU and the heatsink. While you would get a more accurate reading, the gap that it would create would kill the effectiveness of the heatsink. Run a temp sensing program and you will see you are usually a few degrees off from the actual temperature but it is still great for easy monitoring. Just remember you are always going to be showing a few degrees cooler than actual temps. Also, the display says System/HDD/CPU but I use them for HDD/CPU/GPU as I would rather monitor my GPU temp than both HDD and System temp.

This is an inexpensive card for this type of component. Fans are better generally, but they get dusty, are cheap and tend to fail. A heat sink is what it is. It could be limited in performance in the summer if the computer is in a place that gets warm. So as usual, you pick for your situation and usage.

Yes it comes with a heat sink & fan. They are adequate for normal use. However if you intend to overclock I would recommend an upgrade to at least a heat-pipe type of cpu cooler.

You can always add a fan or heatsink? I usually add both to all my cards if they don't have them.

Get a good case with good air flow. At least 6 fans. I have no issues with heat whatsoever.

First, you do not want to put them between the cpu and heatsink. Doing that will not allow a solid "connection" with the thermal paste better the two components. That wing said, I placed them underneath the mobo where the cpu is located. Do not tape the probe to mobo. Just use electrical tape on the insulation of the cable at Tape it to the back wall. Beneath the mobo and have the probe angled towards the cpu. It won't be extremely accurate but it will be very close. For the HDD, you can use electrical tape on the insulation and rape it on the Hdd brackets after you've set and locked the HDD in the case. And angle it so the probe rests on the Hdd. As for the system probe. I placed it so the is just sticking inside the case through the holes used for the cable management. Have it placed as centered as possible for the most accurate temperature. The measurements won't be 100% as a digital probe would be (software that reads the hardware sensors). But it'll be close with a +-5 10 deg C.

I am gaming on the board with a intel 4790 and a GTX 970. I do have an aftermarket cooler (air) on the cpu but honestly probably don't need it. Highest temp in stress testing was 48c. you should be fine with stock heat sink.

No fan is required, passive cooling is just fine. I run two of these 24/7/365.25 no issues.Make sure you get an adequate power supply.

You can get a heat sink, fan (12 volts), and Len's combo on eBay for $20. remember light takes 34V to operate. Do Not Hook The both them in parallel. Yes it comes with a CPU Heat sink.
