4790K @98C Low Load! HELP!!!

Recently, my new 4790K has been reaching temperatures upwards of 98C, when I'm not even running demanding games. My case is the corsair 750D, and my GPU is a r9 290x, but these problems happened 2 weeks before I purchased my GPU. I am running a stock cooler, and the air temperature is around 75F.

Motherboard: ASROCK Extreme 4 z97



I've heard that anything over 1.25V will shoot up temperatures, is there anyway to adjust the volts? I want to manually underclock it if possible, but don't really know how, any help is appreciated

1.77v on an intel CPU. NICE :D 

Fix it in BIOS. Read your mobo manual.

omg, I'm surprised it's not toast already. Why is it at 1.7v?

You misread it. 1.774V is his input voltage. His Vcore is .0949V which is normal. I'd check to make sure the CPU heatsink hasn't come loose or anything like that and make sure the fan is working.

HUH?? 1.7 VCORE ON A STOCK COOLER!?

If you haven't already known, that is insanely high voltage. And overclocking on a stock cooler... your just asking to blow $300 away.

Read an overclocking guide and revert everything to stock ASAP.

EDIT: I didn't see that it is only 0.9 vcore sorry. :) 

But my part about stock cooler still implies, since your going to want at least a good CPU cooler and not the junky ones from intel.

(That makes since now about the Vcore, since 1.7 vcore on a stock cooler should make the CPU shut down immediately.)

Yeah I just noticed that. Absolutely make sure sink/fan.

I made sure my heatsink and fan are both on properly, and the side of my case is off with a fan blowing on it, and the temps are still in the upper 80C

I even let it cool down for 10 minutes, and immediately the temps will shoot up to 80C+

Check the thermal paste on the cooler, it tends to wear off rather easy on the stock cooler if you remove and re-seat it. Infact, just buy some more anyway, its cheap and always useful to have some spare.

I'm getting a cooler this Friday, I'm looking into either some water cooler from the Corsair H series, or an air cooler, specifically the Hyper 212 Evo. I want to eventually overclock my CPU, but I don't know how water cooling works, do I need to change the coolant? Do I need to clean the resivour? Is there that much of a difference?

There is no maintenance (cleaning, refilling coolant) on the Corsair systems as they're closed loop. That stuff only needs to be done on custom loops. The Hyper 212 Evo is great for the price, but a Corsair or other closed loop system would be a better bet if you want to overclock. You can also look at other cooling options by Noctua, Xigmatek, and many many others assuming they'll fit in your case.

ah yes, you're right, Vcore looks ok. Must be the heatsink mounting/paste.

I would also recommend the Evo 212, perfect for o/c up to 4.4GHz'ish (65C).
