i7 6700k at 4.5GHz, h100i stock thermal compound or time for an upgrade?

[buttmademewiser]

So yesterday I oc'd my i7 6700k just a bit to 4.5gHz and is running just fine and stable. The only thing that worries me a bit is that the thermals tend to hop time to time almost up to 80 degree celsius. It's only during very heavy use (gaming + streaming to twitch) but it makes me enough worried to think that should i ease up on the oc or should I change the thermal paste on my h100i? Currently I just have the stock h100i but maybe i should do a change up to arctic silver 5 or mx-4?

Get Arctic MX-4. It performs better than Arctic Silver 5 and is non-conductive/non-capacitive!

As long as it stays below 85 Degrees you are fine. If it does worry you maybe change the thermal paste but it shouldn't need it

According to Intel's Specifications 64C is the recommended max temperature:

k, gonna order mx-4 in a couple of days with some rinsing alcohol and we'll see what happens.

At stock a corsair AIO runs at 2000 rpm. If however you have corsair link installed there is an option to turn it up to 3000rpm "performance mode".

 

BTW if my experience holds you might want to get a spare cooler about the one year mark, just in case.... Fuck corsair.

Just make sure to keep temps at around 75C and you are golden!

Artic silver works brillianty as long as you're using it on something it doesn't react too... I'm pretty sure you missed that bit in your recommendation. It used to be an issue when people were using cheep arse aluminum coolers. It isn't really an issue these days.

 

Any temp below 82-85 degrees isn't going to damage your cpu, and in extreme situations you will hit these temperatures, even if only for a moment.

 

In my experience, air coolers tend to result in lower idle temperatures, but depending on the model, and the thermal dissipation they're rated for, tend not to have as much "buffer" room as a good water cooled system. A good water cooled system will tend not to dispel as much heat at idle, but because of it's higher total thermal dissipation (It's got more room to spread heat through the system) It will perform better when you start pushing the thermal capabilities of your system under heavy load, or overclocking conditions.

 

My opinion on corsair AIO's is due to personal experience. I've had two asetek pumps (The on block pump most AIO's use) fail in two years. The fact that a corsair RMA in australia is the worst nightmare right next to waking up next to macauley caulkin in a french maid's outfit doesn't help the situation.

Gonna have to disagree with you on that one. I've had my H100i for a little over 2 years and it's still going strong. It keeps my 4690k nice and cool even when pumping 1.4v into it.

Mine is a workstation build. It's average uptime is 2 weeks at a time. 1 year of constant use is still within 10% of corsair's MTBF rating.

Still, MX-4 performs better and doesn't react with anything...

I know, but temps should be under 75C most of the time. 85C isn't safe, unless it is only momentary....

Yeah, no, not even close.

 

64c is the max temperature at the case, the CPU sensor is reading from the die which is underneath the case plus the case would always be touching some form of heatsink so 64 at the case is not the same as 64 at the die.

 

6700K has a tjmax of 95°c, that means it will start to thermal throttle itself at 95°c. Generally speaking its advised to keep package temperature around 10°c below tjmax to stay safe.

Still, 85C isn't a temperature that I would be comfortable with... I would go only up to 75C max....

I think there was an ASUS water cooled motherboard with aluminium components on z97 that was the last thing artic silver would have reacted too....Unless you're grabbing a heater core from your car to cool your computer...

 

The two compounds have comparable performance. I'm merely stating that it comes down to preference, and that the so called reactability of artic silver shouldn't be a consideration with any modern computer.

 

And yes, no one is comfortable with a computer that runs 85 degrees all of the time, but a spike to that temperature shouldn't be an issue.

Well Intel manufacture the things to operate at full load upto 95°c so your suggesting you know better than the manufacturer?

 

85°c is fine for a 6700K running at full load, its the top end of fine but its still fine.

I don't run my car at the red line all the time either....

One tenth below the manufacturer specified maximum is not red lining though.

I'm guessing you've never seen how hot Apples MBP runs at regularly? Temps of 90°c are normal for it under any small amount of load, push it to anywhere near full load and it throttles while maintaining 95°c and that's an OEM manufactured laptop.

Check which post was first.... I thought TCase was the max CPU temp

Exactly, because:

1. I don't own and will not own such a shit laptop
2. I haven't watched or read any reviews because IDGAF about it

[TheLaserCucumber]

Lol my 6700K at 4.5GHz with the Hyper 212X tops out at 80C.

[Dango]

Check your overclock. 80C on those chip is around 1.3V. For 4.5Ghz, you should fine at 1.25V or lower.
