i7-7700 on Stock Cooler Running at Extremely Higher Temperatures while Gaming & Stress Test!!! WHY?

[Satyajit Mishra]

I purchased a new i7-7700 yesterday. I installed it on the Gigabyte GA-B250M-D3H motherboard by following all the instructions i.e. stock thermal paste intact, cooler securely latched to the motherboard etc. As soon as I enter BIOS, I saw that the temperature at idle is at 50°C (I'm unsure about the room temperature. But the room was air conditioned, so the temperature would have been low). So after installing a fresh copy of Windows 10 Pro x64, I installed GTA V & the temperature reached 88-90 within 2 minutes of game play (The game settings were at Normal). So I finally decided to do a stress/stability test using AIDA64 Extreme, to my surprise within 5 seconds the temperature reached 100°C & the CPU throttled immediately. As the CPU was overheating, I decided to stop the test.
When my system is idle, the clock speed is at 4GHz (even though the base frequency of this processor is 3.6GHz). The CPU fan keeps getting revved up & down every now & then too, its really annoying.

So can anyone please tell me why is my CPU overheating? I specifically upgraded to this CPU because of its 65W TDP from my old i5-3450 which had a 77W TDP. But the i5 never broke 80°C barrier even when it was being stressed with AIDA64. Please tell me how to solve this issue? Or is my unit defective?

If you are in the bios at 4ghz then the mobo is probably broken. No reason it should be above 1.6ghz. Again, reset to stock settings and get the bios with voltage fix. If it doesn't then return the board.

Tried the BIOS update i.e. from F2 to F4. It didn't solve anything. Also did a reset to stock setting from BIOS by using Load Optimized Default Setting, it didn't help either.

 

[Satyajit Mishra]

You can use a lga1155 cooler but the newer one that came with the i7 should actually be better.

Actually I want to try small changes, to see if this is going to make a difference.

 

[Satyajit Mishra]

Hello... ya me too... your BCK is not backing down... that is a BIO's, CPU, or OS function... do a CMOS clear and/or try a BIO's update... check your OS power setting for the CPU. the intel Speed step is not active in your OS for some reason... as stated above... a CMOs clear will bring the BIO's back to "defaults" and the speedstep will/should be enabled in the BIO's for the CPU.

Tried the BIOS update i.e. from F2 to F4. It didn't solve anything. Will try MB battery removal & CMOS clear soon. FYI the Intel SpeedStep is turned on in my system.

Actually, if the lga 1155 cooler came from something like an i7-3770k or i5-3570k, it'll be slightly better performance as those were 77w cpus vrs the 65w of the 7700, so there should be slightly more headroom on the cooler.

I've the intel stock cooler from my old i5-3450 which is a 77w tdp cpu. So should i give it a try?

 

[Karadjgne]

Can't hurt. Lga1151 and lga1155 are the same mount so swapping coolers for one rated for a higher TDP wouldn't be a bad idea at all.

Fist of all, the default windows 10 high performance power plan puts your frequency always to the max so that's "normal".
If you put the power plan to balanced it will slow down when idle.... (assuming you haven't messed around with the bios)
Alternatively you need to alter the high perf.advanced settings and set the minimum processor state down from 100% to sat 20% (this doesn't work for me and I have to switch to balanced...).
The fact that the processor (in windows) is always at max frequency when idle isn't -too- much of a problem as if it doesn't have workload it doesn't produce that much heat (compared to actual 4ghz workload).
Next, seeing as your voltage is fine, it's safe to say that you have cooling problems... you need to recheck that your heatsink is properly seated... don't put too much thermal paste on it... trust me even no paste is better than too much.
You need to put very little, about a pea size in the middle of the chip...make sure you carefuly wipe the previous paste off and haven't forgotten to remove a sticker or some other protective item from the cpu/heatsink packaging!
Make sure the bracket thingy that holds the cpu is properly secured and that the heat sink's mounts are correctly installed. Put the heat sink on gently and start screwing it in place from opposite directions (such as upper left screw, lower right, upper right, lower left), while not fastening each screw to the max each time.... that way the thermal paste will spread as evenly as possible.
As a sidenote, the 7700 chips are kinda funny and you'll frequently get temp spikes, but don't be alarmed.... at stock settings with the stock cooler you shouldn't pass 85 degrees temperatures when stress testing, assuming you also have ok-ish ambient temperatures and good enough case airflow.
I hope you get that sorted!

You are completely right about the windows 10 high performance power plan i.e. as soon as I switched to Balanced, the CPU frequency went down as low as 0.76GHz. And no I haven't messed around the BIOS.

I finally unmounted the intel stock cpu cooler, cleaned off the thermal paste, reapplied an aftermarket TP & remounted the cooler. Now the temps while stress testing remains below 87 & while gaming it reaches as high as 75. So Maebius was right, I might have screwed up the mounting the 1st time, as I assembled the system in a hurry.

Glad I could help
Depending on where you are (how much hotter is it going to get in your country?), temperature spikes while gaming around 75degrees are just fine. The 7700's are funny that way...
If you monitor all the core temperatures while gaming and they're all -constantly- at around 75 degrees, they will go higher during the summer, so that's something to think about.
You might want to tweak your cpu fan speed to accelerate from lower temps....the stock fan isn't very loud tbh
Cheers o/

FYI, I'm from India & it gets really hot in summer. But as I use this system in an air conditioned room all the time, I'm not too concerned about the ambient temp. Actually I was thinking of purchasing an aftermarket CPU cooler like the 212X, because it has a large heatsink & a 120mm Fan (which would be quieter than the stock cooler's fan).

 

[J_E_D_70]

I already said to back off from Max Performance approx 18 posts ago but congrats on getting it fixed

 

[Karadjgne]

The 212x might not fit in your case, be aware of cooler hights, the 212x is 160mm tall before any adjustments for ram clearance.

Actually i'm an using a corsair carbide 400r, so the 212x will fit into my case.

The deepcool gammaxx 400 cools slightly better han the 212 , is easier to fit & if its cheaper (which it normally is) is a better buy.

How is the Gammaxx 400 better than the Hyper 212X? The 212X uses a bigger heatsink than the 400, the 212X has CDC copper heat pipes where as the 400 doesn't & the 212X's stock fan is also better than the 400. The Gammaxx 400 uses the pushpin latches. To the best of my knowledge the pushpin latches are notorious for causing thermal issues due to improper latching pressure or something.

I am also going to upgrade to your Core i7 7700 tomorrow. I am using a Cooler Master Hyper 212X on a Core i5 7500. Gaming temperature is around 55C.

Since this CPU is only 65W, I suggest you get a Cooler Master 212X as it is tried and tested. If you can get Cooler Master Hyper 412 then even better.

Expect higher temps with the i7 7700 compared to the i5 7600.

 

[gxsaurav]

Expect higher temps with the i7 7700 compared to the i5 7600.

Yes. I do expect higher temperature. Right now I reach 55 C while gaming. Even with a 10C increase in temperature, I will still be within overall temperature limit by Intel.

Well even with a Hyper 212 I hit 83C with mine while gaming. Hottest I've ever seen a CPU get since the Pentium Pro.

Cdc heatpipes and larger heatsink are no guarantee of performance. There's many factors that can affect heat dissipation, such as distance between fins, cfm vrs static pressure if the fan, composition of alloys used in the fins and it's thermal properties etc. If you look at the Noctua u12s, it's relatively small tower, only a 120mm fan, yet outperforms many 140mm towers. The Raijintek Aidos is a 92mm fan tower, yet will also outperform some 140mm towers.
Cdc heatsinks also quite often suffer mismatch of pipes vrs die, this is less often the case with Amd larger die, mainly Intel. It's where you only get 1-2 pipes partially covering the die leaving hotspots, so while most if the die actually sees good temps, you get lines through the die high get higher temps.
Also, the hyper212 series has a miserable mounting system, and the X version has a better quality fan than its predecessor, but still not great. Neither version can touch the Cryorig H7 for anything but price. The gammax 400 is easier for many to mount as it's familiar.

 

[Karadjgne]

I5-3570k @4.3GHz,1.114v on corsair h55 (basically the same as a hyper212 evo in performance) and never see over 54°C gaming, 70°C in p95 26.6 stress. I7-3770K @4.9GHz, 1.32v on kraken x61, 53° gaming. 74°C stress, @4.6GHz, 1.18v, 53° gaming, 70°C stress.
Comparatively, I'd say you probably need to adjust that center knob on the hyper212, tighten it a little, put higher pressure on the die center instead of the edges

 

[Rhettjd]

CPU fan doesn't sound like its properly synched with the CPU I would send it back and explain the issue. Also your clock speed is above what it is supposed to be did you oc this? If so remove the Overclock value

 

[Musuh_Akrab]

i have 6700k running 4.5 ghz @ 1.25v. after stress test aida64 extreme, max cpu package temp is 66 celcius. i'm using cryorig H7 + cryorig cp7.
