Inspiron 5680, i7-8700, needs a better cooler

[MytherZz]

Hello, I just got my new dell pc with a i7 8700, 128gb ssd, gtx 1060 etc. I was planning on using it for rendering and gaming. There is just one problem. This pc is using the Intel Stock cooler or at least I am sure of it, and that stock cooler cannot handle the raw power of an 8700, my pc is getting in the high 80's so I need to know if I can access the back of the motherboard and be able to put a new proper cooler like the Hyper 212 evo, otherwise this thing may be toast.

I just got this new Inspiron 5680 which looked amazing online, but It didn't state what type of CPU cooler it had, as we all know the normal intel stock cooler that comes with a 8700 can't handle that power, so I thought no way they would put this in. But I'm pretty sure they did, and the reason why is because, in normal gaming, my temps are between 82 and 90 all times. I need to know if I can get to the back of the motherboard and install a new cooler in this pc like the Hyper 212 Evo so I can get this under control.

Yeah, it's crazy the industry is still using air-fan-coolers on nice Intel-i7's.

A while back, someone here said one of these Inspiron "Gaming Computers" had a Liquid-Cooler option. If so, maybe you could install that or copy that. 

Have you considered returning it and buying something better? You can get an Aurora-R7 with (Asetek) Liquid-Cooling (and larger 850w PS).

ya that could be a possibility but the budget was $1000, they just didn't specify that it was a stock cooler so I thought something this powerful, they cannot possibly think of putting a stock cpu cooler in it.

Sorry to hear that. emoticon.Smile.title But seriously, may I ask how you come-up with that number ? Are you planning on keeping this computer for a while?

Anyway, if that other poster was right, maybe there is a vacant place near the top for the optional radiator?

I think getting to the back of the motherboard is just the beginning of fun. emoticon.Smile.title

This model can be INTEL or AMD

Liquid coolers tend to start at $90 and go up from there.

If you install standard fan and it complains then the fans use non standard wiring.

Otherwise its standard.

Dell MB Pin Number	Function	Dell wire color	Pin #	INTEL Fan wire color	Description
1	Sens (TACH)	White/Yellow	3	Green	Sens (TACH)
2	+12v	Red	2	Yellow	+12v
3	Gnd	Black	1	Black	Gnd
4	PWM	Blue	4	Blue	PWM
5	Key	unused

Dell May not use standard wiring or Pinouts on their fan headers.

This can lead to self-destruction for a dell fan on standard motherboard or the other way round.

For 3 wire they reverse 12v and tach.

hi, I'm reading this post that interests me. I have an dell inspuiron 5680 (the version with air cooling). I tried to install a fan in the front position as I saw that there was space to do it, then I connected the cable to the motherboard on the FAN2 port. the fan works but it is not read by the bios. however it does not give me any error at startup since the fan is also not dell. I thought it doesn't give me an error because the bios is not really configured to read the FAN2 port so it doesn't give any error. what do you think? furthermore if I also wanted to install a liquid heat sink how can I do it without making me give an error? maybe installing it with the fan on the front?

Bolting a 120 on top of the case fan seems to be used.

80C to 90C is well within the thermal specs of the CPU. It shouldn't be a problem since the CPU is designed to be able to run at those temps. Most of the Gen 8 CPUs run at high temps, in the 80's, when under stress. So your temps are not abnormal for when the CPU is being stressed.

Here is a pic of a liquid cooled Inspiron 5680 with a AMD Ryzen 7 CPU

The ideal solution would be to use a 120mm AIO solution like the Corsair H60 (2018) CPU cooler.  The rear exhaust fan being 92mm keeps your from doing that. 

I see  a front intake fan, is that also 92mm or 120mm fan? If it is a 120 mm fan you can certainly try to install an AIO unit there.

If both the rear exhaust fan and front intake fans are 92 mm then Asetek makes the Asetek 545LC.  Its a nice AIO liquid cooled solution that a lot of mini-ITX Dan case users have installed with the  i7 8700 CPU.  I have installed a couple of them in an XPS 8300 and XPS 8500 and they were very effective in controlling CPU temps.  Installation should be fairly easy and not require removing the motherboard.  I would replace the rear 92 mm exhaust fan with a better fan if you were to go that route.

With a front intake fan and rear exhaust CPU cooler you should not have any CPU temp or case temp problems.
