    Kevered a szezont a fazonnal, pláne szakmai fórumban :W
    Ne terjesszél badarságot, vagy legalább minimum nézz utána alaposan a témának.
    Az idézett szövegben semmi szakmaiság nincs, mert nincsenek hőértékek. Ha elővennéd egy pillanatig a logikádat, akkor magadtól is tudhatnád, hogy 60-90 foknál a 30 nem ugyanúgy hat, mint mondjuk 75-105 foknál.

    Amúgy meg a szakirodalom szerint pont a probléma HATÁRÁN van.

    0-15°C Delta (e.g., 60C GPU, 70C Hotspot):
    This is generally considered excellent to good. It indicates very efficient thermal transfer, likely due to good thermal paste application, proper cooler mounting pressure, and effective cooling solution (heatsink, fans, or liquid cooling). Your GPU is well within its comfort zone.
    15-25°C Delta (e.g., 60C GPU, 80C Hotspot):
    This is often considered normal or acceptable for many modern GPUs under load, especially high-performance cards. While not ideal, it's typically within design specifications and shouldn't cause immediate concern for thermal stress. Some GPUs (especially AMD cards) can naturally have higher hotspot deltas.
    25-30°C Delta (e.g., 60C GPU, 90C Hotspot):
    This is starting to enter the concerning range. While some GPUs might tolerate this for short bursts, sustained operation with such a large delta indicates that heat isn't being dissipated effectively from the hottest points. This can lead to:
    Thermal throttling: The GPU will automatically reduce its clock speeds to lower temperatures, leading to performance loss.
    Accelerated degradation: The repeated expansion and contraction of silicon due to these significant temperature differences can put stress on the solder joints and the silicon itself, potentially leading to micro-fractures over time.
    30°C+ Delta (e.g., 60C GPU, 95C+ Hotspot):
    This is problematic and strongly suggests an issue with the thermal interface material (TIM) or the cooler mounting. Common causes include:
    Poor thermal paste application: Uneven spread, air bubbles, or dried-out paste.
    Insufficient mounting pressure: The cooler isn't making good contact with the entire GPU die.
    Faulty cooler: Issues with the heatsink or heat pipes.
    High hotspot temperatures: Even if the average GPU core temp seems okay, the hotspot reaching 95°C or higher consistently is a sign that the GPU is under significant stress and is likely throttling hard. AMD generally states up to 110°C is "fine" for their hotspot, but a large delta still suggests an issue with thermal transfer to the cooler. Nvidia cards typically throttle around 105°C hotspot. Sustained temperatures close to or above these limits can significantly shorten the lifespan of the GPU.

    Van kérdés? :D
    Szerintem zárjuk a témát.
