The intel i7 4790K runs hot from 75-85C. using 7 cores and part of a core for the cpu. The ambient room temp is 68F. I bought the boxed intel with the intel fan and heatsink which implies to me that if I use their heatsink and fan I should be covered under the warranty for 3 years. In reading the warranty it looks like I should be covered.

I have I higher priced cooler master but did not install it.


I assume that if I don't overclock and use intel's fan and heatsink I am covered under their warranty. Any comments.

I would install that cool master, My CPU never gets over 45C supporting my 3 GPUs running full out. Why would you want to risk burning out that chip? If it runs cooler, less chance of something going wrong. My 2 cents...

Is the the temperature of the cores or the case temp? If that is the case temp that seems high. Even for a stock Intel cooler. If it is the temp of the cores then it isn't to bad.

The K edition processors support overclocking from the factory. That is the extra $ you pay vs the non K editions.
The Intel warranty support process is pretty easy. "Hey Intel this isn't working & is under warranty" "OK do you want a standard replacement or advanced replacement?". I had to have one of my i5-4670K CPUs replaced when it wouldn't boot with memory in the 2nd channel on the MB. I has gone through 3 MBs & 4 sets of RAM before contacting Intel for a CPU replacment.

If you can use almost anything but the stock heatsink, I would use that instead. The stock heatsink is compact but cheap; it's the same heatsink that's bundled with most of their processor line, even the cheaper cpus. In the past, the quickest way to void the warranty was to damage a cpu pin, but those are in the socket now so you really only need to worry about not damaging anything in the socket. I can't remember the last time I broke a cpu, especially that they automatically throttle back when they get too hot, probably somewhere in the 90-100C range. Really the only time I would use the stock heatsink is if I were really short on funds and space and if I knew I wasn't running the cpu full blast all the time. That cpu has a base clock of 4GHz and is supposed to be able to turbo one core to 4.4GHz. But you motherboard might overclock your cpu by default. For example, my motherboard be default runs all the cores at 4.4GHz all the time, so technically that's overclocking. The stock heatsink has a smaller fan that has to turn quicker so it's noisier than a larger fan. The stock heatsink is also small so it's heat capacity is low and doesn't do a great job of dissipating large amounts of heat from the cpu. The stock heatsink's mounting bracket isn't very secure so it's easy to have it improperly mounted which would cause your cpu to run hotter. The stock heatsink's thermal pad is not as good a thermal paste. If your cpu keeps running hot, then the area on the motherboard around the cpu will heat up, possibly reducing the motherboard's life expectancy. So an aftermarket heatsink should be quieter and run cooler, allowing you to overclock more and have a more secure bracket, I would say they bad points are the fact they they aren't free, are larger so they could block ram slots, thermal paste is more difficult to apply than using a pre-applied thermal pad.

It's the core temps as shown by siv64.

woohoo,
Do you know if it is difficult to remove their pre applied thermal pad. Alcohol?

Hal,
I sure don't like the sound of going thru MB's and memory.

My MB was set to use 4.2 GHz but I reset it in bios.

I just took a look at my unused stock heat sink and actually it's probably not a thermal pad anymore. Maybe that was before when the heatsink was all aluminum. Now the core that touches the cpu is copper. The thermal interface material feels more like dried paste. If alcohol doesn't take it off I would just scrape it off, but I'm really not a 'fan' of the stock heatsink for this particular model of cpu, even I don't actually do any cpu work with my processor.

Zalster,
The only reason is so that intel can't point the finger at cooler master or some other mfg. of the heatsink/fan. Also, right now the intel heatsink/fan is running very quietly and that was my chief complaint on my prior rig but that may have involved other factors (MB,bios,etc).

I would install that cool master, My CPU never gets over 45C supporting my 3 GPUs running full out. Why would you want to risk burning out that chip? If it runs cooler, less chance of something going wrong. My 2 cents...

So long as you don't do something like physically beat the CPU to death with a hammer I don't expect you would have any issues replacing it under warranty. When I had to replace my i5 I didn't mention I was using an aftermarket cooler & they didn't ask.
If you completely crazy overvolting the CPU when overclocking you might be able to kill it. I have some CPUs I have actually tried to kill through overclocking & they are still living despite my efforts. :/ It makes me sad when I can't break something. As I am a Test Engineer for a living. So I get paid to break things. Mostly software/firmware, but also a hardware when the need arises.

I suppose the best thing for me to do would be to put in cooler master and then if it is too loud I could go back to the intel heatsink/fan.

Question: Until then, what do I watch out for re. damage to MB or other components other than just watch temps for cpu & gpu cores? If anything?

Coming late to the party... Last year I installed a 4770K with the stock cooler. Under Mint Linux running 8x S@H MB jobs, it would hit 100 C and then throttle back to 3.5 GHz. I installed an aftermarket cooler and it then ran at full 3.9 GHz and is currently running core temperatures of 75-80 C. It's been doing that for nearly a year now.
So just keep an eye on the temperatures (and clock speed if you have a programme to monitor that).

Ivan,
How long did you go with the stock cooler and how long before it was hitting such high temps? Thanks

In re: I7-4790K and stock coolers.
My 4790K is running 4.4Ghz driving two GPUs and all cores running Rosetta. I have a Corsair H105 cooler, and with my room now at 31C, the temps are 75-78C. Mid afternoon they hit low 80s.
I agree with others - install the Cooler Master and keep it as cool as you reasonably can.

A couple of years ago, I did a bone-headed thing when I built my I7-3770K. I forgot to remove the plastic covering the thermal paste on the heatsink before installing it. Temps went to 99C in the first few seconds before the chip powered itself off. I removed the plastic, reinstalled the heatsink, and have been running with the chip ever since. I am sure Intel won't have any problem with lower temps, even into the 80-90C range since over-temp protection is built into their chips.

Ivan,
How long did you go with the stock cooler and how long before it was hitting such high temps? Thanks

Heh, not much longer than it took me to get eBuyer to deliver an after-market cooler. :-) I don't recall exactly how long it took to start bouncing off the rev-limiter when I fired up S@H, but I believe it was measured in seconds rather than minutes...

---

Thanks Ivan,

I just installed my cooler master. The temps went from (today) 79-86C to 58-68C.
Wow! Thanks everybody.

The noise. Well it is a bit louder but not as bad as the old rig so I can live with it.

Shame on intel for not putting a big black and yellow sticker attached to that fan and cooler explaining what is what. People putting together a rig without the benefit of a group like this are gonna make big mistakes. [Even the ones with common sense]
