My 5640 cooler only heats and don't cool is part of the fan bad? Or what could be wrong. J.D.

If you're reversing your cord to heat and the fan doesn't turn, are you using the original motor or a replacement? The cooler reverses the polarity to heat or cool but some replacement motors won't run both directions. Without a resistance check and being able to see the cooler first hand, I can't offer any better help.

Could be, if the flow of air is not going over the cooling area it cannot cool it down. If this part fits your cooler buy it and try, it could be a really cheap fix...

If all you're getting is heat, and the fan is running, the most likely thing is that the D.C. power connection is backwards. Try unplugging the cord from the cooler, turning it over and plugging it in the other way. Thermoelectric coolers generally use solid state components that provide heat with one polarity and cooling with the opposite polarity. In either case the fan should be running. If it isn't, you may need a new motor.

Sorry my fan was not working too,for a week one of the fan stopped working ,since we throw the box we can't return it to amazon,they have to improve this product because the appearance is good but the performance is bad.

I'm sorry but I'm really not sure. It's been awhile since the fan was installed. Your best bet is to check with the manufacturer.

Hopefully, you have air slots or vents in the hotter components. If you have air vented slots on the sides and bottom, mount the fan below, if you have vented slots on the top, mount the fan unit above to draw the heat away.If you have room in the rack to space the components from each other, that is best. It is a little noisy, but works well. If you can, put the fan closest to your most critical component that is effected by heat

Mine did that initially. Up and down between 49 and 53 and the fan kicking in every couple of seconds. I raised the temperature to 55 and it stopped doing that.

That sucks. When mine is on it's set to Cool/Low/62/No Ion. It still doesn't actually cool particularly well (as my review says), but it does stay on indefinitely. You could try "power cycling" it. Unplug for 10 minutes or so (to make certain the compressor is reset) then try again. Works for routers, lol. Also consider maybe its an electrical issue. Try plugging in to a different circuit or something? Or is something bouncing air back into it that could be causing it to get wrong air temps? I'm just throwing out ideas here. :)

Make sure that the fan is not block. It does take a while to cool thing. Do you have the Powerchill model or the other one. We returned the other model because it never got my husband's sodas cool enough.

Fyi people, if your system is already overheating this isn't going to stop it! You need to open it up, clean it and inspect to ensure your internal fans still work.

i have the same problem. bought 3 fans less than a year ago and 2 failed in the last week. i will try and change the fuses but have put Amazon on alert just in case.

Are you sure you wired it correctly? Maybe you mixed up the heating circuit with the cooling circuit? If that's not it, I'd get a new one. Why take a chance?

Yes mine does the same thing. My guess is that my fan wore out because the first few days it was loud and annoying, but eventually stopped. Only then did my computer begin to overheat and shut off when I play certain video games for as little time as 45 minutes.

You're definitely right! I think the chip outputs too much heat. What I did is undervolted the cpu from the BIOS and also disabled the AMD Turbo Technology, and now it's so much cooler and quieter. Temp on idle around 30-35 load 50-55. Lowest degree was 25. That's insane with the stock fan!

did you install it, sounds like a loose connection, need to strip back more insulation on the wires that go from stranded wire to solid wire maybe, if not the fan is most likely defective

im not sure if its my fans i put in or the cooler for my processor but i want to say 7-8 maybe less

That is I believe your cooling fan Not working properly. It is behind the lamp at the back of the TV. Fairly easy access.

Hi Mike, I didn't have this problem but make sure all your crimps at the connections are tight. Also make sure your stainless steel radiator probe is positioned near the radiator inlet or upper hose as it may be. It should be pretty straightforward and maybe the module itself is defective. Good luck I'm sure you'll figure it out. By the way these fans do a great job and I've noticed no heating problem since the installation in fact it almost runs too cool.Dan

I did not have this exact problem but there has been a rash of bad circuit boards axcording to the tech. Its unusual yours works intermittent ly versus complete failure. If I had to guess it sounds like you have a cooling problem and theset shuts down to save itself. Try putting a small fan behind it.
