I just upgraded the CPU in my QNAP TVS-H674 NAS from a 12400 to a 14600. The unit is using passive cooling. Everything is running fine with the idle temperature around 77 degrees. Tried some load, but the temperature seems to be steady. My precious CPU ran around 20 degrees cooler.
Does anyone see any issues with this running 24/7 or should I consider something like the i7 13700T?
It is probably throttling at that temp. Bad idea.
I7 13700t is I think one of the optional cpu’s for that NAS.
Quick Google Search:
The maximum operating temperature, or [TjMax], for an Intel Core i7-14600 is 100°C. While temperatures up to 100°C will trigger thermal throttling to prevent damage, it is ideal to keep your CPU operating well below this limit, ideally in the 70-85°C range under heavy load, to ensure longevity and consistent performance.
77 degrees should be just fine.
77 is way to high IMO for idle
I have 13900t and my idle is around 50 in an 874
Ok, so I also tried a SilverStone Technology NT07-1700 ultra-low profile cooler connected to the cooler plug on the board used for the rear-cooler running at 100%. Lowest I got was 75 degrees.
I’m going to try the 14700t next (can’t find the 13900t). Will post my results here next week or so when I get the new chip.
Did you buy a real 13900t, or one of the engineering samples? I find them hard to find.
I took out the 14600, wasn’t comfortable with the temperature. Tried the 14700t but the system didn’t recognize this processor (guess it’s too new?). Put the 12400 back in the system and now I’m around 47 degrees.
Deciding whether to hunt for the 13900t, go for the widely available 13700t or maybe the 13500?
Are you on the newest BIOS?
14700t is an i7, you are already melting with a i5 14600.
The T processors are 35W base, you put in a 65w part.
Reddit has a couple people running 14400, maybe try to find any i5 14xxxT processor and use the newest BIOS.
Yes,
Latest bios.
The T processors should be fine (all of them) because of the lower power consumption. I’m guess that the BIOS doesn’t suppor the 14th gen T processors.
I did return the 14600; and I read some success stories on the older forums (and above) with the 13th Gen T processors (like 13900t and 13700t). Your recommendation for the 14xxxT doesn’t make sense since the the latest BIOS doesn’t seem to support these. I’m going to go for the 13xxxT (probably 13700T) and report back here.
What are you using? I do appreciate your reply.
Others have run the 14x00t to my knowledge from the old thread. I bought a genuine 13900t and not a sample. They are hard to get for sure. I got mine on ebay
I do have the latest BIOS to the best of my knowledge. The 14700t was stuck on the ‘Hardware Initializing’ part (and I read somewhere that in the past this also indicated a non-recognized CPU). It’s possible the chip was faulty I guess. Anyway, I’m going to settle on the 13700t - will post my results when I’ll obtain one (they go for around $250 on eBay, a genuine 13900t is double around $500. Not worth the additional money for me).
13700t installed. Recognized correctly in the system. Average temperature is 58 degrees. So far, so good.
Glad to hear!
As long as the cpu uses the same socket (Intel website lists which socket every cpu is designed for) and same wattage (Intel website again) a given cpu will probably work. If it is the same series, it will almost certainly work. This NAS originally had 12000 series so glad to know 13000 series works!
Temps down to 50 degrees after enabling C-States!
I can confirm the 14700T does NOT work.
Did not know that h674T may be compatible with 13th and 14th series. So I chose to go with an i7-12700, which has same TDP as the originally installed 12400 i5.
Idle temperature runs around 45°C degrees, with a room temperature at around 23°C.
There is a huge performance difference. It is especially noticeable with VM’s, which I currently have two running.
If I may recommend, definitely go with an 12700 i7. It also costs less.
