6700k plus H155i temperatures and voltages.
6700k plus H155i temperatures and voltages.
I'm just needing other peoples opinions on if these temps, multipliers and voltages all check out.
I'm able to get my 6700k with the Corsair H115i AIO up to 4.5GHz with 1.3-1.305v (crashed once somehow at 1.3 so bumped a bit just in case) and see temps go up to about 77c with this cooler and 64c on a chilly day.
but just going up to 4.6GHz with 3.5-3.505v (once again, didn't crash on 3.5 but went up once again to be safe) and I get up to 85c with a randomly jump to 88 for a second.
4.7GHz almost instantly blue screens at 1.4v and the temps I imagine would be way too much.
Do you think these temperatures are normal? I opted to replace the stock fans on the cooler for some Industrial Noctua 2000rpm fans too (not because of this, when I first got it). The ambient temperature is around 20-25c when I test these besides that one chilly day.
I've reapplied thermal paste the the cpu numerous times (Noctua NT-H1) and that seems fine.
I moved my radiator to the front of my case as I have a open fan style GPU which caused an additional 10-20 degree increase. (If you're skeptical about that, here's a link to a video explaining it in detail: https://www.youtube.com/watch?v=xNAMxZgvves)
Are these temps normal? Is my cooler doing it's job? Are the voltages alright?
I have tried researching this but it's so riddled with random voltages, random multipliers and random coolers I couldn't figure it out.
Thanks!
EDIT: I also forgot to mention that I use a maximum on 75% on my fans to reduce noise.
They mentioned that anything over 80 is not good. They tried changing the thermal paste and it helped. The radiator placement should be at the front, though you can adjust it. They asked about the type of fans used in the pump—were they the original ones?
The_Staplergun :
You need to bring back the original component. Anything over 80 is not good.
I tried reinstalling my pump with fresh thermal paste and it helped. The radiator should be positioned at the front, just like you have, but you can push or pull it. It should make a difference. What type of fans are installed on the pump? Are they the original ones?
I set the multiplier back to 4.5, which keeps it under 80 even during stress tests.
I’ve re-seated and reapplied the paste many times without seeing any real improvement.
I use two Noctua NF-A14 Industrial PPC 140mm 2000RPM PWM fans in pull mode (mainly for dust filtration).
The setup looks good for the fan. For confirmation, use a Corsair link to ensure your pump is operating correctly. Check the pump temperatures; if they stay below 30°C or lower during idle, and the pump speed matches expected ranges (around 1800 or 2900 depending on settings), it may indicate a specific model issue. It’s possible you have a faulty CPU. The maximum safe temperature is 80°C. Running Prime95 v26.6 with SMALL FFT will provide an accurate load temperature reading. If it goes above 80°C, your system is overheating and needs inspection. Avoid exceeding 1.4 volts; also, don’t overclock beyond 1.35–1.375 unless necessary. For a 5.0GHz target, you’d need around 1.375 with 1.34V, which hits the 80°C mark.
the temperatures need to stay under 80C on cores when under load. your cooler is only mediocre compared to a liquid cooler, just like all other CLC models from corsair, nzxt, etc. if you're seeking good cooling power, top-quality parts, a stylish look, and expandability, the Swiftech H220 X2 or H240 X2 offers the best value for money.
The_Staplergun :
That's fine on the fan setup.
I'd recommend using corsair link to verify your pump is running properly. See what the pump temps are. If they're not around 30c or lower at idle, or the pump speed is really low (it should run at either ~1800 or ~2900 depending on settings, there's no curve), it could be your particular model.
It could also be that you've got a bad CPU.
80c is the limit. Prime95 v26.6 SMALL FFT setting will give a realistic load temp. If that exceeds 80, you're running hot and need to check your equipment.
Do not by any means exceed 1.4 volts. I also highly recommend not overclocking that high if it requires more than 1.35 maybe as high as 1.375.
For me to do 5.0ghz I need to do 1.375, but it runs excessively hot. I can't go higher than 4.8 on a 7700k at 1.340 volts. That puts me right at 80c.
The pump is on performance mode. Runs fine.
I don't think it's a bad CPU considering it can do 4.5 at 1.3 fine and low temps (except on hotter days).
I don't do realistic tests, I do hard stress tests for maximum heat. In games my CPU doesn't even hit 60. Sometimes under 50.
That's all normal for the 7700k to reach those multipliers.
One thing I want to point out though is that over 80 is fine. You can find many people that will tell you that and a lot of people if your CPU can handle the heat will go as high as 1.5 on the voltage. Your standards are a bit low.
notes:
the temperatures need to stay under 80C on cores when under load.
your cooler performs poorly in most cases with liquid coolers, just like other CLC models from Corsair, NZXT, etc.
if you're seeking good cooling power, top-quality parts, a stylish look, and expandability, the Swiftech H220 X2 or H240 X2 offers the best value for money.
this really depends on the multiplier, ambient conditions, and voltage levels.
the term "under load" can vary—some people just play games, others push the system to its limits.
i usually keep my temps around 50 when gaming AAA titles and under heavy stress tests.
i’ve noticed Swiftech sometimes has quality control problems, and most of the comparisons I’ve seen match older models like the H110i or H100i.
i should note that i limit my cpu fans to no more than 75% for audio reasons.
My guidelines are the suggested boundaries to avoid chip damage. I won't expose my chip to temperatures above 80 for long periods. That's comparing it to putting your hand in a hot oven—it will burn you if you keep it there. More power to you. I'll focus on lasting longer.
Well, the outcome really hinges on the multiplier, ambient conditions, and voltage levels. The term "under load" can vary greatly—some experience light gaming while others face intense stress tests. I maintain a stable temperature around 50°C during AAA gameplay and heavy stress tests, which aligns with the results I’ve recorded.
I’ve noticed Swiftech’s products often have quality control concerns. The tests I’ve reviewed consistently compare their models to older versions like the h110i and h100i, all of which had comparable radiators.
I should also note that I keep my CPU fans at a maximum of 75% for audio clarity. Reaching 80°C on the cores isn’t a concern—it’s simply a threshold I avoid.
Testing is rigorous; I use extreme loads (such as prime95 combined with other stress tests) to ensure stability. This helps confirm that any additional components will perform adequately.
Concerning Swiftech, there are several quality questions: radiator, pump, CPU block? These are top-tier parts. From what I’ve observed, the H220 and H240 from Swiftech outperform most competitors by 5 to 12°C while producing significantly less noise.
Comparisons with other brands like Atek/Coolit (used by Corsair, NXT, TT, Arctic Aloys) are misleading. A pump from Asetek or Coolit can’t be fairly compared to a DDC pump from those brands. Similarly, a copper/brass radiator can’t be matched to an aluminum one.
I understand why some people opt for the Kraken x62 for its aesthetic appeal, but otherwise, Asetek/Coolit are budget options with limited longevity—typically 2 to 5 years. Swiftech or EK AiO products will still function well for a long time.
Here are some revised versions of your text, keeping the original meaning and tone while varying the wording:
Well, that outcome really hinges on several factors like the multiplier, ambient conditions, and voltage levels. And when it comes to "under load," it can range from casual gaming for some to a rigorous stress test for others. I maintain a stable temperature around 50°C during AAA gameplay and heavy stress tests, which aligns with the results I’ve shared.
I’ve also heard that Swiftech has quality control problems, and all the tests I’ve seen have been compared to older models like the h110i and h100i—those are much older radiators, and they performed quite similarly. I didn’t mention that I keep my CPU fans at a maximum of 75% for sound reasons. Running at 80°C on the cores isn’t something you want to exceed—it’s just a safety limit.
The testing process is intense; I push systems with extreme loads (like prime95 combined with Heaven). That’s how I confirm everything else holds up.
Regarding Swiftech... What kind of quality issues have I encountered? The radiator, the pump, the CPU block—these are top-tier parts. From what I’ve observed, Swiftech’s H220 and H240 consistently outperform most competitors by 5 to 12 degrees Celsius at significantly lower noise levels.
You can’t just compare that to the pumps from ASEKET or Coolit (which make Corsair, NZXT, TT, Arctic Aloysia), or a DDC pump. You also can’t compare a copper/brass radiator with an aluminum one. I get why some people might pick the Kraken x62 for its aesthetic appeal, but otherwise, ASEKET/Coolit is a budget option with a lifespan of just 2 to 5 years.
Swiftech or EK AiO will still be reliable in the long run. The temperature you see is largely determined by these factors. Most of what I’ve seen shows only a 2 to 5 degree difference, especially when comparing older AIOs to this newer model.
My cooler doesn’t produce excessive noise from the pump, and I haven’t noticed any issues. I don’t hear anything unusual, and it’s cheaper than expected. It’s almost as if you’re paying more for extra precision and better materials. Still, a 2-year warranty is pretty short—especially with a 5-year guarantee? That would be more typical.
